Shadow Magic is an obscure but powerful form of magic believed by some to be related to the schools of Illusion and Mysticism. It was originally harnessed by Azra Nightwielder, who was the first to discover that shadow was not simply an absence of light, but a reflection of possible worlds created by forces in conflict. Shadows can be produced by mundane forces such as light hitting a rock, or by more powerful forces such as nations at war. Shadows are the records of the clash, past, present and future of these forces. Shadow Magic involves the manipulation of shadows to affect the forces creating it. At its strongest, it even has the capabilities of reaching into and affecting the multiverse. Shadow magic has the potential to carry a high price for its usage, for its nature is to turn on their casters, and shadowmages are often distrusted because of this. Shadow Magic is common around the Western Reach area, but is only occasionally used elsewhere. It is often harnessed by "Nightblades".
Shadows can be coalesced into shadow-equipment such as the Shadow Stabber blade, armor such as Shadow Gloves, or even jewelry like Shadowrings. They can also be absorbed to strengthen and empower the mind, although this can have physical and mental side-effects, such as out-of-body experiences, distortion of ones senses and the shriveling of skin. In the same vein, shadows can be infused into the body as well, magically improving one's strength, speed or endurance. In both cases, it is possible to feel consciousnesses fade away as a shadow merges with the shadowmage's own. Despite these boons, Shadow Magic can distort and corrupt living beings, making them into "an echo of what's right". Another usage of Shadow Magic is the creation of decorative objects, such as statues. It is possible to link the shadows of beings together, allowing for communication over distance, although the process of such is painful. Azra Nightwielder referred to this as an "umbric connection". Nightblades used Shadow Magic to teleport short distances ("stepping through shadows"), or to drain other people's life force..
Shadow Magic can be used in the creation of Shadow Gates. These are magical barriers often used to protect treasure, and can only be bypassed through the use of arcane relics known as Shadowkeys. Circa 3E 397, only eleven Shadowkeys were known to be in existence. Shadow Gates can have a variety of appearances, from portal-like or door-like to outright invisible. Shadowkeys also have other unique uses, such as one which was used to resurrect Volstok Violet, restoring him to life from a zombified state. Shadowkeys can also be used to "unlock possibilities in the shadows", calling upon shadows to bolster the wielder's mind or body.
Shadowmages can use Shadow Magic to visit shadow realms, alternate versions of the world, to aid a different version of themselves. Similarly, shadowmages can summon different versions of themselves to their own world. Death in a shadow realm will break the connection, although it is also possible to escape with light-based magic. The Sea Sload Z'Maja summoned shadowy reinforcements from shadow realms during her fight with the Undaunted
Besides Shadowkeys, there are a number of other relics related to shadow magic. The Shade Sickle is a Daedric weapon created by Bretons. It had the unique ability to split the living from their shadows. Just like some shades, those struck by the blade were slowly and gradually stripped of the ability to think consciously, and turned into hapless beings akin to thralls.. It was associated with Daedric Prince Nocturnal and was a powerful instrument of her will. Despite its common appearance, the blade was preternaturally sharp and filled those who gaze at is with a deep sense of foreboding. Z'Maja was given an arcane amulet by Nocturnal, obtaining great power and control over the shadows whilst in its possession.:146
Shadowrend is another Daedric artifact, typically taking the shape of a two-handed ebony axe or claymore. Whilst this weapon has appeared in different places, such as the Shivering Isles or Eastmarch, the method of obtaining it has been typically the same. A would-be wielder must face off against and defeat their own shadow, only then would Shadowrend be claimed. This weapon is known to bear enchantments which either damage health or inflict weakness to magic.
The Onyx Cleaver is a battleaxe said to be made from petrified shadows and was known to drain the stamina of those hit by it.
In the First Era High King Durac of Craglorn ruled over eight lesser kings, one of which was a shadow mage known as the Shadow King.
The Psijic Order's records on the original shadowmage, Azra Nightwielder, are unreliable as they have been tampered with shadow magic. However, according to them, around 2E 230, Azra attempted to manipulate his own shadow to such an extent that he would meld all possible versions of himself, crossing over from a singular existence to all the existences in shadow. He seemingly met his end after a battle with Redguard soldiers, so his experiment never came to fruition. During his absence, other shadowmages strove to take his place and continue researching the science of shadow, including Pergan Asuul and Skelos Undriel.
Circa 2E 582, the Veiled Heritance returned Prince Naemon from the dead as the Shade of Naemon. The Shade began the process of creating the Shadow Wood, a mirror realm of Valenwood inhabited by shades and corrupted spirits. Naemon intended to corrupt and replace Valenwood with his shadowy realm, but was killed by the Vestige and their allies, destroying the Shadow Wood in the process. In the same year, the Spider Cult took over Fungal Grotto in western Stonefalls. Here, worshipers of Mephala enthralled travelers with shadows, turning them into beings of darkness loyal only to the Cult. This was possible via the usage of an artifact of Mephala known as the Obsidian Husk. With the aid of the Undaunted, Defender Two-Blades of the Fighters Guild destroyed the Husk and ended the Cult.
In the Gold Coast, the ruins of Lord Faleria's complex were discovered and excavated by researchers. Unbeknownst to them, a long time ago Lord Faleria had performed a dark ritual on the fortress, consuming the entire castle in eternal darkness. Shadows rose like smoke from the earth, dissolving architecture, men, and mer. Some formed man-like shapes and attacked any foes in sight. Others opened up like rifts, and the world vanished inside them. These same shadows rose up again, attacking the excavation team and the mercenaries hired to put an end to them. Lord Faleria himself rose again, possessing the body of a colossal minotaur lord named Limenauruus. Ultimately, both the minotaur and the Lord were defeated, allowing the excavations to continue. During this time, a powerful shadow mage and former Dark Brotherhood Silencer known as the Black Dragon was hunting down and executing members of the Brotherhood. She eventually confronted The Vestige, sending out multiple shadows with different tactics to attack and kill the Hero.
Later on, the Daedric Prince Nocturnal tried to take control of the Clockwork City. Using her shadow magic, she gave Sotha Sil's Shadow sentience, which then replaced him as ruler of the Clockwork City. Meanwhile, one of the Clockwork Apostles, Chancellor Gascone Dusant, sought to deliver the Skeleton Key, which had been accidentally found by a Factotum beneath the Brass Fortress, to Clavicus Vile, only for the Key to be stolen by the Blackfeather Court. The Vestige, assisted by Divayth Fyr and the Clockwork Apostles, unveiled the plot, but were unable to reclaim the Skeleton Key before it was taken by Sotha Sil's Shadow. Using the key, Nocturnal and the Shadow attempted to seize control of the Clockwork City, but were stopped by the Vestige, Divayth Fyr, and Proctor Luciana Pullo, who rescued Sotha Sil by defeating his Shadow. Sotha Sil then gave the Skeleton Key to Divayth Fyr for safekeeping.
Nocturnal subsequently took control of the Crystal Tower. With a technique she stole from Sotha Sil involving utilizing life energy as a power source, she planned to use the life energy of Nirn, and then the energy of the other Daedric Princes afterwards, to amplify the Crystal tower and make her shadows limitless. If she succeeded, she would have spread her influence across the multiverse, and would have been unstoppable. Nocturnal's plan was foiled by the Psijiic Order and the Vestige, with the assistance of the two betrayed Princes (Mephala and Clavicus Vile) and the champion of Meridia known as the Golden Knight. The divine power of Meridia's Dawnbreaker was then used to restore the tower's stone, Transparent Law. Sotha Sil then made negotiations with both Mephala and Clavicus Vile and the two have agreed to a compact to put an end to their direct meddling.
Around the same time, the Welkynars, under the command of Relequen captured a Sea Sload named Z'Maja—a necromancer who was a member of a group called the Abyssal Cabal, consisting of several Sea Sload that sought to sink all of Summerset. The Welkynar took Z'Maja to the Cloudrest Aerie, much to the dismay of the city's inhabitants. This proved to be their downfall when Z'Maja utilized dark magic to trap all of Cloudrest in a dense shroud of mist. The mist drained the life of the people, leaving the lower district completely intoxicated. The Divine Prosecution was forced to barricade the city until Z'Maja was dealt with, while Olorime of the Welkynar was able to keep all of the people safe in the upper district. Olorime enlisted the help of the Undaunted to defeat Z'Maja. Each of the Welkynars that had been corrupted by Z'Maja's shadow magic was defeated, and the Sea Sload was slain. According to some reports, Olorime was the sole surviving Welkynar and was forced to recruit new initiates into the order. Other accounts mention that the Welkynars escaped the corruption of Z'Maja's shadow magic and survived.
Shadow Magic played a central part of the War of the Bend'r-mahk in the Third Era. The large amount of conflict caused by the war manifested itself as a powerful entity known as the Umbra' Keth, or "Shadow of Conflict". Jagar Tharn and Pergan Asuul competed to gain control of the monster for their own use. The Soul of Conflict, a questing hero under the guidance of Skelos Undriel and a returned Azra Nightwielder, used the power of the Star Teeth to destroy the creature.
