The Ice Fields (also called the Winterhold Glaciers) are a region of glacial fields found along the coast of Winterhold, in the province of Skyrim. The glaciers are found on the mainland around Alftand, Saarthal, and Frostflow Lighthouse surrounded mostly by the Winterhold Mountains, with other glaciers found around the capital going east. The ice fields continue in the Sea of Ghosts through a series of arctic permafrost-covered glacial islands and icebergs along the Northern Coast, some meeting the Broken Cape. Glaciers on the mainland allow access to the see through steep glacial canyons. Many adventurers perish in the glacial fields that surround the city.
Icereach is a small isolated island located in the Sea of Ghosts. It is considered a part of Skyrim and it is a contested territory between Reachfolk Witches of Icereach Coven and Nords. The fort on the island was built by Nords in order to protect whalers from Orc pirates but was eventually acquired by the Reachfolk and served as base of operation of the Icereach Coven until 2E 582 when it was defeated by combined forces of Lyris Titanborn, the Undaunted guild and the Vestige.
The Iggnir River is a body of water located in southern Solstheim. It runs south until its mouth empties into the Sea of Ghosts, just east of Fort Frostmoth.
Before the Red Year of 4E 5, the Iggnir was a large river which ran through the Hirstaang Forest and the Isinfier Plains. It ran south all the way from its source, the frozen Lake Fjalding. It was filled with horkers, who made their way from the coast and up the three rivers of Solstheim to their breeding grounds at Lake Fjalding. The Telvanni settlement of Tel Mithryn was founded west of the mouth of the river some time before 4E 5.
Following the eruption of Red Mountain, southern Solstheim slowly began to be engulfed by ash. Several decades of this resulted in the destruction of the Hirstaang Forest, and southern Solstheim was transformed into ash wastes. The Iggnir River was reduced to little more than a shallow stream. It no longer flows from Lake Fjalding, instead beginning in the northern ashlands. The native fauna fled north, and the Iggnir instead became home to several endangered Silt Striders who had been brought over from mainland Morrowind by Dunmer refugees, although they did not flourish on the island. The Emperor Parasols from Tel Mithryn also spread to the banks of the river. By 4E 201, the southern coast of Solstheim had been poisoned by the continuing ashfall, killing fish.
Ilayas Ruins is a ruined citadel built on a seaside hill of Malabal Tor, in the province of Valenwood. The keep is occupied by an ancient order of lightning wizards called the Stormwardens, who defend the coast from foreign invasion and operate an ancient Ayleid artifact called the Sphere of Storms, a potent orb that utilizes weather magic to manipulate the waves of the coast and supply water for crops. The entire ruin was built around the focus of the Sphere of Storms, and the Stormwardens will go through great lengths to protect it.
The Ilessan Hills is a political entity found in the province of High Rock, in the region of the Iliac Bay. It is a landlocked region that is known for its ancient forests and pine country. It mostly consists of a vast mountain range that spills into neighboring countries and wetlands in the northeast section of the barony. The region is the home of the local Glenmoril Wyrd, an ancient coven of witches that venerate the natural world and worship the less-feral aspects of Hircine, the Lord of the Hunt.
The Iliac Bay (also spelled Illiac Bay, sometimes called Starfall Bay) is the large bay separating the southern coast of High Rock from the northern coast of Hammerfell. Southwestern High Rock and northern Hammerfell are often referred to collectively as the Iliac Bay region. The Imperial Navy's Northwest Fleet is charged with its protection.

Lake Ilinalta is a lake in west-central Falkreath Hold, in the middle of Skyrim's pine forest. It is the source of the White River, and a notable Skyrim landmark. The town of Helgen was less than a day's ride to the southeast, and the Hold's capital of Falkreath is directly south. The Imperial Legion used to have a fort along its shore, until the entire structure mysteriously sank into the water in a single day. According to local legend, the place is cursed and travelers are known to go missing.
Ilinalta's Deep (formerly known as Fort Ilinalta) is a ruined fort on the lake shores of Falkreath Hold, in the province of Skyrim. It was built sometime in the Fourth Era by a disenfranchised teacher from the College of Winterhold, Malyn Varen and his followers. It eventually sank into Lake Ilinalta and flooded from within. Ever since then, local fisherfolk have believed that the whole lake is cursed.
Ilunibi is an old sea cavern found on the West Gash on the island of Vvardenfell in Morrowind. Ilunibi served as one of the many lesser bases for the Sixth House during their resurgence in the late Third Era. It was a quiet retreat and omitted from any Imperial maps that were present at the time. It is thought that many natural caves form a series of nodes and capillaries that originally pulsed with the divine essence of the Aedra that created Nirn. This may explain the origin of Ilunibi.
The Imperial City, (also known as Cyrodiil City, the Imperial Capital, the Capital, just Cyrodiil and as the City of a Thousand Cults) is the capital city of Cyrodiil and the entire Empire. Culturally Nibenese, it is described as the heart of Tamriel.
A thriving city, its flooded lower dwellings are sailed by gondolas and riverboats. Moth Priests walk the streets in clouds of ancestor moths. House guards bearing exceptionally long daikatanas keep watch over the streets. The city proper is located on City Isle, which lies in the center of Lake Rumare, but continues across the lake and merges into ruins left by the Interregnum and the villages of the southern Niben River. The city stains the mouth of the Niben red with the tinmi soil of Rumare's shores.
Imperial City Prison
The Imperial City Prison (also called the Imperial Prison or the Imperial Dungeons) is located in the Prison District of the Imperial City, connected by bridge to the Market District. It is infamous for its impregnability, although several secret escape tunnels connect up to the ancient subterrane and the prison sewers beneath. It is the headquarters of the Imperial Legion.
Imperial Province of Akavir
The Imperial Province of Akavir was a short-lived province created in 3E 288 during Emperor Uriel Septim V's invasion of Tsaesci, Akavir. Septimia, a Tsaesci port town, was the first colony of the province. The settlement of Ionith was the invasion's headquarters.
The province encompassed the lower stage of a large river, along which both of the settlements were located. The surrounding land consisted of rich, well-watered fields. The four legions present during the invasion constructed a road between Septimia and Ionith.
The province was abandoned in 3E 289 due to extreme weather conditions and Tsaesci attacks. Uriel V died in battle during the retreat. The area was retaken by the natives and has never been revisited by Imperial forces since.
The Imperial Reserve is a grassland area extending across the southern section of the Colovian Highlands. It lies west of the Great Forest and extends west towards the Gold Coast. The Imperial Reserve is sparsely populated, containing only a few small hamlets such as Hackdirt and Weatherleah. The Reserve is prime hunting ground due to its flat land and sparse trees.
The Infernium Forge is a Dwemer ruin known for producing pitch-black animunculi that radiate fire, giving them a burning hot appearance. The Dwemer scholar Guylaine Marilie noted the vamidiums and spiderlings from the site are unusual and distinctive, indicating that they all came from the hand of a single Dwemer artisan. Constructs originating from the Infernium Forge had found their way into the hands of collectors across Tamriel by 2E 582.
Indoranyon (Dark Elvish for "Blessed Greenland") is a stronghold located on the coast of Vvardenfell, in the province of Morrowind. The fort is one of the most notable landmarks on that stretch of the coast. Indoranyon is mentioned in the historical-fiction book, Poison Song, written by Bristin Xel. The ruin's propylon chamber links to Falensarano and Rotheran.
The Inner Sea (also called the Inland Sea and the Vvardenfell Rift) is a body of water that separates the mainland of the Imperial province of Morrowind from the large island of Vvardenfell. It stretches from the Bitter Coast and Ascadian Isles regions in western Vvardenfell all the way to Azura's Coast in the east. It meets the Sea of Ghosts twice: the two meld together near Azura's Coast, and again near the large and icy island of Solstheim northwest of Vvardenfell.
There are conflicting reports on the origins of the Inner Sea. Some sources accredit an eruption of Red Mountain to its creation, whereas Vivec's Sermons point to the usage of the Numidium circa 1E 700. However, some sources attest that the Inner Sea was present before both the first major eruption of Red Mountain and the activation of the Numidium. Furthermore, Topal the Pilot left behind maps of the Inner Sea dating to the Middle Merethic Era, far before the first Dwemer colonies.
The main port of the Inner Sea on Vvardenfell is Ebonheart, with minor ports being Hla Oad, Gnaar Mok, Molag Mar, Tel Branora and the Imperial outpost of Seyda Neen with its lighthouse Grand Pharos guiding mariners. The Imperial Legion once held a strategic outpost called Fort Firemoth on an offshore island of the same name, but it was overrun by an undead army and never reclaimed. The Inner Sea is home to a species of bioluminescent and sentient Land Coral that grows exclusively on the land around it. The fields of Vivec's Antlers is the most notable example of a site containing this species of Land Coral. Vivec's Antlers was also a battlefield in the Second Akaviri Invasion of 2E 572, for the final battle involving the Snow Demons of Kamal and their invasion of the province of Tamriel.
The coast of Vvardenfell is rugged and treacherous, with shipwrecks scattered among the menhirs that protrude from the water. It has been a major center of smuggling operations by the Camonna Tong and other groups.
Ione is a small village in the province of Cyrodiil, a short distance southeast of the village of Pell's Gate.
It was established at the end of the Oblivion Crisis, and is named after Imperial Legion Captain Tertius Ione. In the center of town are the large, ivy covered ruins of an Oblivion Gate. This gate opened in the middle of Captain Ione's Legion encampment. He and his men went into the gate, but were never heard from again until a Bosmer soldier closed the gate and appeared in the forest weeks later. He had been driven insane, and died days after he was recovered.
During Captain Ione's absence, a few of the legionaries who stayed behind in the camp built what were originally intended to be temporary buildings. Instead, a town grew up around them. It is filled with structures made of rotting wood, but is still a favorite town of Crown Prince Attrebus, who inherited a hunting lodge there.
Ionith was a large Akaviri settlement used as a headquarters by Emperor Uriel Septim V's invasion of Akavir in the year 3E 288. It was originally a Tsaesci town farther upriver from Septimia, but was found abandoned and was taken over by the invasion force to be re-founded as a colony of the short-lived Imperial Province of Akavir. A road linked the settlement to Septimia.
Due to the terrible, almost unnatural weather suffered leading up to the Battle of Ionith, communications between the two cities was lost as the river dried up and the garrisons along the road were lost to raiders. The Emperor was besieged, and led a valiant march towards Septimia in order to retreat. This was the last direct contact from the Expeditionary Force, but survivors of the Battle say that the Tsaesci surrounded them and Uriel V was killed, "cut down by enemy arrows as he rallied the Tenth [Legion]'s shield wall". The settlement was reclaimed by the Tsaesci and has never been revisited by Imperial forces since.
Irkngthand (meaning Dark Steam Gardens in Dwemeris) is a Dwemer ruin tunneling beneath Lake Yorgrim in The Pale hold of Skyrim. Irkngthand is home to the only known depiction of the Snow Elves before the Dwemer corrupted them into the modern Falmer. The statue was built in secret by the Falmeri slaves and adorned by the two Eyes of the Falmer, which are giant gems of enormous value said burn into oneself upon viewing their magnificence.
Irkngthand is theorized to be associated with the Clan Rourken, and was built in the Hoagen Kultorra style like many of the other strongholds of the Northern clans, featuring an Arcanex and a Deep Venue layout in its grand cavern. It is rumored to be one of four Dwemer cities with an entrance into the underground cavern known as Blackreach (found just across from Raldbthar and its Great Lift), however no evidence of this entrance has been found, if it ever existed at all. Large portions of this ruin were flooded following Thieves Guild activity in the area in the year 4E 201.
Irranhu is a small island in the Yokudan archipelago, between the Azurian Sea and the Sea of Pearls. It is just north of Samara, off the southeast coast of Akos Kasaz.
The Isild River is a river in northern Solstheim on the Felsaad Coast.
Before the Red Year of 4E 5, the Isild River ran northwest from the frozen Lake Fjalding until it merged with the Harstrad River at the foot of the Moesring Mountains. The river then continued to its mouth on the icy Felsaad Coast, west of Skaal Village. It was reportedly a beautiful part of the island, at the right time of year.
The cataclysms of the Red Year substantially changed the landscape of Solstheim. Many of the landmarks remained the same; the river is still west of Skaal Village and flows from Lake Fjalding to the coast. However, the Isild and Harstrad rivers no longer meet. Instead, each empties separately into a small bay on the northern coast.
The Isinfier Plains are the central tundra on the island of Solstheim that stretches from Thormoor's Watch in the west to the eastern coast, between Thirsk and the Hirstaang Forest. The Moesring Mountains, Lake Fjalding and the Isild River form the northern border and Bloodskal Barrow, Brodir Grove and the Sun Stone form the southern border. Most of the Isinfier Plains are covered in snow and frequently endure savage blizzards especially to the north, near the Moesring Mountains.
Flora in the region is diverse and includes Belladonna, Holly, Solstheim Pine trees and several species of shrub just to name a few. However, it is the fauna in the region that is what makes the Isinfier Plains an excellent hunting ground. Various species include the common grizzly bear, snow bear, common wolf, snow wolf, tusked bristleback, grahl, white horker, draugr, ravens and Rieklings.
The unique river systems and sheltered bays of the Isinfier Plains makes the region an excellent place for various smuggling operations and camps for reavers, berserkers, Fryse Hags and hunting parties of the Skaal and Thirsk. Many people call the dozens of ice caves in the Isinfier Plains home. The area also includes magnificent tombs like the Jolgeirr Barrow. The Altar of Thrond is located in the north of the Isinfier Plains, on the banks of the Harstrad River.
After the Red Mountain erupted in 4E 5, Isinfier Plains became the border between the southern ashlands and the northern, intact part of the island. In 4E 201, the reconstruction of the Temple of Miraak began in the region, but was left incomplete after the defeat of Miraak by the Last Dragonborn.
Isle of Contemplation
The Isle of Contemplation is a small island in the Summerset Isles, located off the northern coast of Vafe. It is a recursive island, being found within a lake completely within Aurdion, whose waters flow from the Diceto River to the Auridon Strait. It is described as magical and serene, and one of the most beautiful places on Tamriel.
One of the last members of the Veiled Heritance on Summerset sought refuge on the isle.
Isle of Craghold
The Isle of Craghold is an island within the province of High Rock. It was inhabited during the Third Era.
At some point during the War of Betony between years 3E 402 and 3E 403, Craghold was besieged by the forces of Sentinel for several days. The siege was broken by the forces of Daggerfall forces under Lord Bridwell, who liberated the island. Siege of Craghold and Battle of the Bluffs were both victories of the Bretons.
Isle of Gold
The Isle of Gold is a group of small islands located in the center of Lake Honrich in the Rift region of Skyrim. The islands are interlinked with bridges and are similarly connected to the mainland via a bridge from the south shore of the lake.
Isle of N'Gasta
The Isle of N'Gasta is a small island west of Stros M'Kai, named after its infamous resident, the Sload necromancer N'Gasta. The isle suffers from frequent storms and is always a gloomy place, inhabited by bats and mysterious creatures with tentacles.
A chain of islands called The Spine extends from Stros M'Kai's northern shore, and at its end a mysterious bone-like boatman once ferried travelers to and from the Necromancer's Isle. A large graveyard covers most of the isle, and it was likely once used by the first Redguard settlers to bury criminals. This was a tradition brought over from Yokuda, to prevent the criminal's evil spirit from tormenting the living. The Necropolis, the largest structure in the graveyard, spans the width of the island, barring those who seek the old wizard's tower. This tower, sometimes called N'Gasta's Tower, is situated on an islet at the isle's southern tip.
During the reign of Thassad II, N'Gasta came to the isle and made it his. After the Battle of Hunding Bay in 2E 864, he began raising skeletons and zombies, including those who died in the battle. Later that year, Cyrus came to the isle and accepted a delivery job from N'Gasta. He came back after he learned that his sister, Iszara, was last seen on her way to N'Gasta to ask for assistance. He discovered N'Gasta's treachery and after killing the necromancer, entered the realm of Clavicus Vile to bargain for her soul. With Iszara saved, they headed back to Stros M'Kai together.
Isle of Red Mist
The Isle of Red Mist, also known as the Isle of the Red Mist, was among the places visited by the infamous Captain Wereshark in the Second Era. The isle was inhabited by criminals and cannibals, who practiced graphic rituals and worshipped ancient matrons of the sea. By the time Captain Wereshark and his crew had rescued several painted cannibals from the island, it was ruled by the Queen of Bones, Crackteeth.
Ivarstead (also known as Hillgrund's Steading) is a small milling town, situated at the eastern base of the Throat of the World, on the western edge of the Rift, built on the western shore of Lake Geir. Pilgrims and travelers often pass through, as the town is located at the beginning of the 7,000 Steps to High Hrothgar. Northeast of Ivarstead lies the Nordic ruin known as Shroud Hearth Barrow.
Ixtaxh Xanmeer (formally known as Ixtaxh-Thitithil-Meht, which translates into "Exact-Egg-Cracker" in Jel) is a sunken xanmeer ruin located on the coast of Murkmire, in the province of Black Marsh. It is a great stepped pyramid, said to be one of the most extensive stone-built sites in the region. It is rumored that the ruins contains a plethora of jewelry and treasure, among these items of interest was the Kajin-Jat Crystal, a vakka stone that was used in rituals by the Ancient Argonians.
