Caldera was an Imperial charter town just north of Balmora. It was built to service the nearby ebony mine, providing the miners with homes, entertainment, and other services. The town was ruled largely from the Caldera Mining Company's fortress to the northeast. The buildings, which had Imperial and Nordic architectural influences, formed an inverse "L" shape between two large guard towers. While Dunmer presence in Caldera was almost non-existent, a large contingent of Orcs lived in the dilapidated Ghorak Manor (along with an unusual Scamp who was a merchant and claimed the house was his). Notable institutions in Caldera included an Imperial Cult altar, a Mages Guild branch, two general merchants, a blacksmith, a tavern, and one of the few Imperial-style clothiers in Vvardenfell.
Camlorn is a major city of High Rock, located on its western coast. The city was previously the center of a kingdom, also called Camlorn, which was founded in 2E 302. It was once predominately a Nordic city, but was assimilated by the Bretons over time.
In 2E 541, the city was sacked by a horde of Reachmen led by Durcorach the Black Drake. After the Reachmen were defeated, Camlorn, along with Daggerfall, Shornhelm, Evermore, and Wayrest, signed the first Daggerfall Covenant.
In 2E 582, Camlorn was ruled by Duke Sebastien. During that year, the city was badly damaged by Faolchu the Reborn and his werewolf army. They were defeated by Daggerfall Covenant forces and the Soulless One soon afterwards, and the city was eventually rebuilt.
In 3E 63, the Prince Pelagius, who would go on to become Pelagius Septim II, visited the city of Camlorn to woo the daughter of King Vulstaed, Quintilla, regarded as the most beauteous princess in Tamriel. She would later go on to become his second wife.
Cann was a ruin in the Shivering Isles. Though the initial origin of Cann is all but unknown, the last notable inhabitants were a group of Manic idealists who brought residents of the Isles (and sometimes beyond, in the case of Beldring of Palgania) to the ruins to be housed and pampered for days on end. Ultimately, the group who oversaw this project fled the ruin, and the bloodbath that they caused.
Lake Canulus is a small lake in the far east of Cyrodiil, between the Silverfish and Panther Rivers. It is surrounded by old forts, mines, camps, and caverns. A great monastic complex of the Alessian Order was once built along its shores, but it was razed during the War of Righteousness, and much of its archives were destroyed. The Ayleid city of Varsa Baalim was located near the lake before it plunged into the ground in the early First Era.
Cape of the Blue Divide
The Cape of the Blue Divide is the waters of the Aldmeri Dominion around Summerset Isle. Stros M'Kai is noted for its strategic position near the waters. "By the Blue Divide" is a common saying among Altmer.
Castle Ebonheart (or Ebonheart, after the mainland city of the same name) was the seat of Imperial authority in Vvardenfell. From this city, the Duke of Ebonheart, Vedam Dren, and his Grand Council determined law and policy for the Vvardenfell administrative district. The Imperial Chapels served the Duke, his retainers and the castle's garrisons, and were also an administrative center for Imperial Cult presence.
An Imperial Guard unit protected the Duke, and the Hawkmoth Legion was also garrisoned within the walls of the castle. Much of the business in Vvardenfell, which concerned either the Empire or House Hlaalu, was conducted in Castle Ebonheart, as the Hlaalu Grandmaster was the Duke himself.
Because the East Empire Company was chartered directly by the Emperor, its offices, warehouses and docks were adjacent to the castle, and its security was assured by the Imperial garrisons. The provinces of Skyrim and Black Marsh maintained diplomatic missions in Ebonheart, the latter mainly in concern for its citizens, due to the fact that the Morrowind province was exempt from the abolition of slavery.
Castle of the Worm
Following the Soulburst caused by Mannimarco in 2E 578, Nirn was cast adrift so that Molag Bal could merge it with his realm of Coldharbour. Although acting as his loyal servant, Mannimarco planned to usurp Bal's place as the God of Schemes and rule over both Nirn and Coldharbour. The Castle of the Worm was built using dark magics and the slave labor of Soul Shriven as a monument to the necromancer's hubris. Although Mannimarco himself continued to rule from the Imperial City, the Castle was used as a prison and cattle pen. Overseen by Worm Cultists, countless mortals were sacrificed to Molag Bal at the Castle, losing their souls to become Soul Shriven. Their corpses were then used as material for the creation of undead servants to guard the fortress. A small Soul Shriven village called the Wretched Squalor sprung up outside the walls of the Castle.
One of the Castle's many prisoners was Chancellor Abnur Tharn of the Elder Council. Despite submitting to Mannimarco following the necromancer's betrayal of Emperor Varen Aquilarios, Tharn was eventually removed from his position of power in the Imperial City and confined to the Castle. He was given meaningless tasks, overseeing minor Worm Cult cells on Tamriel and sorting soul gems, and was kept alive for political reasons only until such time as he could be disposed of. By chance, in 2E 582 following his escape from Coldharbour, Varen Aquilarios came into possession of a magical orb that Tharn used to communicate with a subordinate. Seeing it as a chance to escape, Tharn promised to reveal the location of Sai Sahan if he could be extracted from the Castle. Aquilarios created a portal to Coldharbour for Lyris Titanborn and the Soulless One, who were then able to enter the Castle through its cistern with the help of Sir Cadwell. Fighting through the Daedric, mortal and undead guardians, the intruders succeeded in freeing Tharn from captivity and were teleported out by Aquilarios after a brief confrontation with Mannimarco's projection.
After his failure to secure the Amulet of Kings from the Five Companions later that year, Molag Bal learned of Mannimarco's plans to replace him. The King of Worms was pulled into Coldharbour to be tortured for all eternity, and although he later escaped from the Prince's clutches, it can be assumed that the Worm Cult fell out of favor within Coldharbour. The fate of the Castle of the Worm is unknown following the failure of the Planemeld.
Castle Volkihar is an ancient castle perhaps dating back to the Merethic Era or the early First Era. It is located on an isolated island off the coast of Haafingar Hold in Skyrim, near the border with High Rock.
The Ceporah Tower is an ancient structure on the Isle of Artaeum, an island originally in the Summerset Archipelago. The Tower serves as the headquarters of the monastic Psijic Order, who call Artaeum home. While parts of the Tower were constructed by the Psijics, its foundations are far older, having an entirely unique architecture, and was built by unknown ancient beings. Directly beneath Ceporah Tower lies the Dreaming Cave, which houses a portal that can be used to travel to any realm of Oblivion; it has been used for this purpose by many, including Sotha Sil—a member of the Dunmer Tribunal—who made a compact with many of the Daedric Princes in the late First Era.
Ceporah Tower is used by the Psijics in many of their rituals, and is known as the location beneath which Vanus Galerion confronted Mannimarco about the latter's increasing fascination with necromancy and soul-trapping. It was this confrontation that led directly to the founding of the Mages Guild.
Cespar (also spelled Caspar) is a large island off the western coast of Hammerfell, south of Herne. Tralan the Two-Blade, a Redguard swordsman who became one of Emperor Titus Mede I's most valued men, hailed from Cespar.
Ceyatatar (meaning "Shadow of the Fatherwoods" in Ayleidoon, originally named Ceya-Tar) is a crumbling Ayleid ruin in the wilderness between the Imperial City and Skingrad. The entrance leads into the central dome of a great underground edifice once dedicated to Magnus, where ancient magic still casts a blue shimmer onto the faded white walls.
The Chain is a group of at least three islands in the Eltheric Ocean, south of Hegathe in Hammerfell and west of Stros M'Kai. The two smaller islands trail off to the west. By the late Third Era, the islands appeared to be considered part of Hammerfell in certain maps.
Cheydinhal is a city in eastern Cyrodiil whose architecture and culture contains heavy Dunmer influence due to its close proximity to Morrowind's border. Located in the foothills between the Valus and Jerall Mountains, Cheydinhal sits on the northeastern edge of the Nibenay Basin, a river valley of tributaries to Lake Rumare and the Niben River.
Cheydinhal consists of three districts: Cheydinhal Castle, Market, and Chapel. The dominating feature of the city is a tributary of the Corbolo River, which bisects the city from north to south. The river is crossed by three bridges: a single bridge to the north connects the Market district to the Chapel district, while two smaller bridges to the south connect the southwest plaza and Chapel via a small island park.
The Clockwork City, also known as Sotha Sil, is a metaphysical clockwork realm created by Sotha Sil, one of the living gods of Morrowind, to replicate the mythic structures of Nirn in metallic miniature. It supposedly exists "outside space and time", and in the physical world, it is represented in the form of a Clockwork Globe that is no larger than a good-sized netch, and requires an individual to be magically shrunk to enter. Although represented in miniature, a whole world lies from within as the realm is expansive from the inside.
The Clockwork City's exact location is shrouded in mystery, with the city itself being described as a "metaphor made manifest". Statements about where the city is located more accurately describe ways to get to the city, rather than the physical location of the city itself. Sources from various eras had many theories of how to get to the city, many which lead nowhere. As a result, The city had attained a mythical status with some even doubting that it even exists. Some theorized that it could be located somewhere in the southern swamps of Morrowind, close in proximity to Tear, or beneath the settlement of Ebonheart. Of all the rumors and speculation on where the Clockwork city is located, only two direct entrances to the city were confirmed to have actually existed: The first was a rift that opened up in Abanabi Cave beneath Tel Fyr in 2E 583, but it was rumored to have been sealed by the great mage, Divayth Fyr. The second was the Clockwork Globe, a Tamrielic representation of the city itself. Around 2E 583, the globe was located in Seht's Vault within the Dwemer ruins of Bamz-Amschend, deep beneath the Mournhold Temple in Deshaan. It was a location theorized to have been chosen due to Sotha Sil's admiration of Dwarven industry. It is possible that the location of the clockwork globe changed throughout time.
The means of entering the Clockwork City vary beyond that, and many Skilled mages were able to create devices that allowed them to teleport into the city. The mage Barilzar created the Mazed Band, which enabled its wearer to teleport directly to the city. Telenger the Artificer created the Hyperagonal Locational Determinator, a device that could pinpoint any desired location in the entire Gray Maybe, even those protected by magical defenses including both Artaeum and the Clockwork City. Other skilled mages were occasionally able to teleport to the city when conditions were right. A number of the city's inhabitants arrived in the realm unintentionally and spontaneously.
Citizens of the city referred to outsiders as exodromals (from beyond the celestiodrome, or the "Nirn Above"). To gain citizenship in the Brass Fortress, one had to find a sponsor among the city's inhabitants who would be willing to vouch for them. In most cases, new citizens had no way to return to Tamriel, and consequently had no choice but to stay in the Clockwork City forever. The Clockwork Apostles have the device known as the Doors of Egress, which allows them to teleport anywhere in Tamriel. Despite the portal back to Tamriel existing, citizens were told that it did not exist. Some felt that living in the realm was a miracle, while others considered it an unending nightmare.
The Clockwork City is believed to have been constructed sometime after the rise of the Tribunal at the Battle of Red Mountain in the First Era, when Sotha Sil harnessed divine power from the Heart of Lorkhan with the use of Kagrenac's Tools. Sotha Sil created the Clockwork City for various reasons, all of which were to serve a noble goal. He saw the Aedra's creation of Nirn as flawed and in order to perfect it, he built the Clockwork City to ensure the redemption of Tamriel, unify competing forces, and destroy the Daedra. From his city, Sotha Sil had hoped to "forge the future" and "reshape the world".
Cloud Ruler Temple
Built by Reman Cyrodiil's Akaviri Dragonguard at the founding of the Second Empire, it served as their headquarters. Even as they became known as the Blades, the Emperor's agents continued to occupy Cloud Ruler Temple until the end of the Third Era. Legend has it the swords of those slain protecting the Dragonborn were hung within the Great Hall of the temple. The archives of the temple were believed to have been the primary repository of the oldest Blades lore.
Cloudrest is one of the eight major city-states in the province of the Summerset Isles, situated on the highest slopes of Eton Nir. Cloudrest is colloquially known as the "Aerie of the Altmer", because it overlooks the great plains of Summerset from the highest mountain in southwest Tamriel. It is the home of the Welkynars, who are a knightly order dedicated to protecting the Summerset Isle, and known for their Gryphon mounts.
Coldharbour is a realm of Oblivion created and ruled over by Molag Bal, the Daedric Prince of Domination. As befits his sphere, Bal's realm is a desolate, apocalyptic image of Nirn, which is achieved by both mocking imitation and outright theft of parts of the mortal realm. It is inhabited by Daedra and the eternally-tormented souls of mortals called Soul Shriven. Descriptions of the plane vary widely, but all accounts agree that Coldharbour is a dismal, cold, and largely lifeless realm.
College of Winterhold
The College of Winterhold is a school for magic in the city of Winterhold. Its campus is imposing and fortress-like, arranged around a large central courtyard and reachable only across a narrow stone bridge. It functions much like the Mages Guild in other parts of Tamriel, but is a resolutely independent establishment separate from the Guild. The College holds documents dating back as far as the late Second Era, though the College itself is even older. It is said to have been founded in the First Era by the legendary mage Shalidor, although it is one of many dubious feats attributed to him. One of the oldest reliable mentions of the College comes from the early Second Era.
The College is a selective institution, which allows entrance only to those students who prove themselves adept at the magical arts. However, once a student earns admittance, they are granted more freedom of experimentation than in the Mages Guild, with even Necromancy regarded as an acceptable arcane practice. The College's main building is the Hall of the Elements, which is used for all kinds of magical practice. It holds the famous Arcanaeum library as well as the Arch-Mage's quarters, while accommodations for students and faculty are provided in separate buildings. Beneath the college campus lies the Midden, a remnant of the college's past where many of its greatest secrets lie.
The Colored Rooms are a realm of Oblivion, created and ruled over by Meridia, known as the Daedric Prince of Infinite Energies. From what little has been seen of the Colored Rooms, they seem to resemble a cross between a coral reef and a vast field of floating stones, strewn with colorful trails of dust or cloud. The "ground" between the stones looks like luminescent water, but is solid enough to walk on. Aurorans are the spawn of Meridia, although they have close ties to the Ayleids. It can be assumed that they dwell in her realm of Oblivion.
The Colored Rooms were formed when Meridia fled Mundus with her fellow Star-Orphans. However, instead of fleeing to Aetherius, Meridia went into the Void, where she was chided by the Daedric Princes for her trespass. Bending the light of Magnus, Meridia then carved her own sphere from the chaos of the Void, creating a new plane of Oblivion.
Colovia is the western part of Cyrodiil and is known for its austere, martial culture and rugged population of Nordic descendants. The borders have moved over time, but in the Third and Fourth Era the region comprised Anvil, Chorrol, Kvatch and Skingrad counties, and the Imperial Reserve. Back in the first and second eras, the modern Skyrim hold of Falkreath was, at times, included as one of several kingdoms making up western Colovia.
Most of the population in the later eras resides in the cities of the south, although there are scattered farms and settlements throughout the area. The region around the sea port of Anvil is known as the Gold Coast. The region around Skingrad is known as the West Weald, and is well known for its vineyards and tomato farms. The city of Kvatch lies on a rocky outcrop between Anvil and Skingrad, with the Colovian Highlands stretching away to the north. The city of Chorrol is the main population center in the northern part of Colovia, a hilly, forested region sandwiched between the Great Forest and the Colovian Highlands.
The Colovian Highlands are a hilly, forested region of Colovia on the western edge of Cyrodiil. The borders of Hammerfell lie to the northwest. The Gold Coast and West Weald border the region to the south, and the Jerall Mountains and Great Forest are to the east. The town of Chorrol can be found in this region.
The Coral Forest is an iconic landscape on Summerset Isle, located south of Shimmerene. This place consists of a dense collection of petrified coral which creates a strange, labyrinthine landscape of collar pillars along the island's eastern shore, where coral crabs, mud hoppers and reef vipers hatch and thrive.
In 2E 583 Tilcalar, Earl of Clavicus Vile, one of the three leaders of the Court of Bedlam, and also Aldarch of the Monastery of Serene Harmony, appointed by Kinlady Avinisse, tried to activate an Abyssal Pearl, most probably with intentions of creating an Abyssal Geyser near Shimmerene to begin to sink Summerset Isle under the sea. His plans were fouled when the Soulless One killed him and Valsirenn magically moved the Sload artifact to Artaeum.
The Corbolo River is one of the largest tributaries of the Niben River, which it joins at the northeast corner of Niben Bay. It rises to the southwest of Cheydinhal, flowing southeast until it merges with its tributary, the Reed River, then south, then finally southwest.
Corgrad Wastes (originally just Corgrad) is a sunken city located along the northern coast of the Summerset Isle, in the province of the Summerset Isles. Corgrad was once a prospering city, before it was heavily afflicted by the Thrassian Plague in the late First Era. Its ruins have since mainly been and inhabited by scavengers.
During the Alliance War of 2E 582, a large town was located at Cropsford. It was primarily a farming settlement, and had a shrine dedicated to Zenithar. Settlement was strongly encouraged by the townsfolk, many of whom were not natives of Cyrodiil and decided to stay after passing through. The town was constantly plagued by the undead from Culotte, and the Bloody Hand Tribe of goblins. Cropsford was initially located within the territory held by the Ebonheart Pact, although the town and the nearby Drakelowe Keep changed hands many times over the course of the war. It was feared at the time that the encroaching goblins planned a full-scale attack.
The town's troubles were clearly too great to overcome, as the settlement was later abandoned. In 3E 433, the land was offered cheaply by the government, and a Breton family from High Rock purchased it. Their plans to build a farm at Cropsford were dashed when they arrived to discover that the land was the center of an ongoing goblin war between the Bloody Hand Tribe and the Rock Biter Tribe over a stolen totem. The Champion of Cyrodiil put an end to the war, allowing construction to begin. It was hoped that Cropsford would one day become a thriving town.
Crowhaven is a fort located along the Gold Coast of Cyrodiil, in County Anvil. During the Second Era, it belonged to the Jarol family and was known as Jarol Estate. It later went on to become the home of the Lord Loviducus, but fell into ruin and became home to a den of feral vampires.
Crypt of Hearts
The Crypt of Hearts is a multi-level mausoleum located in northern Tamriel made up of dank, winding passageways filled with strange creatures. As befits such a place, its exact location is uncertain, having entrances in both High Rock and Skyrim. The city of Shornhelm, near its High Rock entrance, is sometimes referred to as "the Keeper of the Crypt". The Crypt of Hearts was originally built by the Ayleids, and was known as Agea Relle. Some time during the Second Era, the Agea Relle was turned into a school for teaching the practice of magic. The school was founded by the Altmer Nerien'eth and his wife Alanwe. This school was short-lived, as Nerien'eth killed everyone at the school, including his wife, after coming into possession of the Ebony Blade.
In 3E 397, due to the ongoing War of the Bend'r-mahk, a Shadow of Conflict was created deep within the crypt. This Shadow of Conflict, or "Umbra' Keth", could be controlled by a powerful Shadowmage. Pergan Asuul, one such Shadowmage, sought to control the monstrosity for his own ends, as did Jagar Tharn, who was posing as the Emperor Uriel Septim VII. An unknown hero, under the guidance of Azra Nightwielder and Skelos Undriel, recovered the seven Star Teeth in an effort to destroy the Umbra' Keth. The hero descended into the crypt on the Skyrim side of the border, near the city of Dragonstar. All but one of the crypt caretakers had fled, as the Umbra' Keth's presence had caused the dead to rise. The hero battled the final incarnation of Pergan Asuul in the crypt, and placed the Star Teeth on their pedestals in the Vault of the Heavens. The hero then lured the Umbra' Keth from the third level of the crypt and into range of the power of the Star Teeth, which weakened the shadow creature and allowed the hero to destroy it, preventing it from falling into the hands of Tharn, or anyone else who would misuse it.
The crypt was also used as a hiding place for one of the shattered pieces of the Staff of Chaos throughout the Imperial Simulacrum. The Eternal Champion, on a quest to dethrone Jagar Tharn, sought out the crypt. The Brotherhood of Seth in Camlorn, with the aid of a map that the champion recovered, were able to find an entrance to the crypt. The entrance was at the end of the northern bay in High Rock, near the city of Shornhelm. The champion recovered the piece of the staff on the fourth level of the crypt.
The Crystal Tower (also called the Crystal-Like-Law or Lawful Crystal) was an ancient, mystical structure located near the northern tip of Summerset Isle, northwest of Cloudrest. It was built by the early Aldmer as a monument to their ancestors, and was considered sacred to the Altmer. Before the construction of the Arcane University, it was the pinnacle of magical learning in Tamriel. The top of the Crystal Tower was reserved for interring the dead. The southernmost tips of the Dragon's Teeth Mountains of mainland Tamriel could be seen from the top parapet of the tower. The interior of the tower was white and radiated light. It contained a Great Library and a treasury with many ancient tapestries and other relics. The Crystal Tower was famed for its animal pens, which held many different creatures from all across Tamriel.
The Crystal Tower was one of the mythical Towers that stabilize the Mundus. The Crystal Tower was present in all realms of the Aurbis simultaneously, acting as a gateway to all realities. The Tower's Stone was called Transparent Law, which was placed at the Tower's summit on Nirn. It has been theorized that control of the Crystal Tower—through Transparent Law—could grant one omnipresence in the entire Aurbis. In the early Second Era, the three Daedric Princes Clavicus Vile, Mephala and Nocturnal conceived a plot to steal the Heart of Transparent Law, making a deal with the Sea Sload K'Tora to make Iachesis—the leader of the Psijic Order—steal it using mind magic. Iachesis, however, managed to hide the Heart within himself. Circa 2E 583 the three Princes discovered this and killed Iachesis. However, Nocturnal betrayed the other Princes by taking the Heart for herself. She attempted to take control of the Crystal Tower by herself, but her plan was foiled by the Psijic Order and the Soulless One, assisted by the two betrayed Princes and a champion of Meridia. The divine power of Meridia's Dawnbreaker was then used to restore Transparent Law.
I'ric Harad Egun was once the Archmagister of the tower. Tame trolls were employed as guards in the tower. During the Imperial Simulacrum, Jagar Tharn hid a piece of the fractured Staff of Chaos within the tower. The Eternal Champion located the tower by recovering a magical diamond from the Temple of the Mad God. The diamond was the source of power for the Mages Guild of Lillandril, and with the diamond the guild was able to locate the tower. The Eternal Champion entered the tower and recovered the piece of the Staff of Chaos. The tower was an early target for The Beautiful, but they failed to destroy it and moved on to easier targets. During the Oblivion Crisis (known to the Altmer as the Great Anguish), refugees fled to the Crystal Tower to fortify against the Daedra hordes. The Daedra broke through the refugees' defenses and used magic to topple the tower.
During the Alessian Slave Rebellion, Culotte became home to one of the Ten Ancestors, Ayleid statues originally held in the White-Gold Tower which were dispersed to cities across Cyrodiil for safekeeping. Culotte subsequently fell into ruin after the Ayleids' downfall.
The ruins of the settlement were once known to attract undead of all kinds. Circa 2E 582, the nearby settlement of Cropsford was occasionally threatened by the undead that flocked to Culotte, prompting the townsfolk to periodically clear the ruins. Eventually Culotte was cleared of undead. In 3E 433, the Champion of Cyrodiil entered the ruins and retrieved the ancient Ayleid statue, causing the dead to rise from their graves and once again plague the ruins. The statue was later sold to Umbacano.
The only notable structure on the island is the ruins of Cosh Hall, which now serves as a human stronghold. The dominant vampire bloodline of the region is Selenu. Although the island is uninhabited, it was considered a separate political entity until the Warp in the West, when it was most likely subsumed by the massive expansion of the Kingdom of Sentinel.
Cylarne was a ruin in the Shivering Isles at the end of the Third Era, located on the Isle of Flame. It is the oldest known ruin in the Isles, and is rumored to be the original capital of the Shivering Isles. The ruins of Cylarne are home to the Cold Flame of Agnon, which is fed by the altars of Rapture and Despair.
In 3E 433, Sheogorath's Champion was sent to Cylarne to relight the Great Torch in New Sheoth, which was extinguished by the coming Greymarch. The Champion put an end to the conflict by manipulating a planned attack from the Saints, and brought the holy Flame back to New Sheoth.
Cyrodiil, also known as the Imperial Province, Dragon Empire, Starry Heart of Nirn, and Seat of Sundered Kings, and Cyrod in Ayleid, is a province in the south-central region of Tamriel, and the home of a humanoid race known as Imperials. The center of their Empire and seat of governance, Cyrodiil is also known as "the Heartland". The capital of Cyrodiil, and of the whole empire, the Imperial City, is located on City Isle in the center of the province, which bears the location of White-Gold Tower, possibly the most renowned monument of Tamriel. Despite some accounts describing Cyrodiil as a jungle, it primarily has a temperate climate. One scholar of the middle Second Era attributed this discrepancy to errors made during the transcription of historical texts, while another speculated that White-Gold Tower itself gradually adapted the climate to suit the region's inhabitants. Later sources asserted that Emperor Tiber Septim altered Cyrodiil's climate upon his apotheosis.
