Artaeum is the third largest island in the Summerset archipelago, located south of the Moridunon village of Potansa and west of the mainland village of Runcibae. It is best known for being the home to the Psijic Order, perhaps the oldest monastic group in Tamriel.
Around the end of the First Era, at about the time of the founding of the Mages Guild in Tamriel, the isle disappeared entirely, only to reappear 500 years later. Members of the Order who were thought to have died when it vanished reappeared as well, refusing to reveal where Artaeum had been during its time away.[OOG 1]
Artaeum is said to have idyllic orchards and pastures, the still and silent lagoons, the misty woodlands, and the unique Psijic architecture that seems to be as natural but wondrous as the surroundings. The Ceporah Tower, a structure built by a civilization several hundred years before the Altmer, is one of Artaeum's more prominent features.
- Arch-Mage Savos Aren of the College of Winterhold claims that he was but an Apprentice when last a member came to the college from Artaeum, approximately 100 years before the Civil War in Skyrim.
- Iachesis notes in 2920, Rain's Hand that Artaeum will be "leaving in the next few years, and return when the land needs us again, perhaps in another age."
