Pyandonea
From the OblivioWiki – your guide to everything Oblivion
The Island Home of the Maormer(sea elves), located south of Tamriel.
Orgnum, the leader and self-styled "King," according to the legend was a phenomenally wealthy Aldmer nobleman, who used his finances to launch a rebellion against the powers of the land(Aldmeris). He and his followers were banished for this to a place separated from Aldmeris by an impenetrable mist, Pyandonea, "The Veil of Mist". This boundary proved so effective that the followers of Orgnum never again disturbed their former countrymen.
This Island was described as a "sea jungle". Massive plateaus spilling over with vegetation that formed mazes around valleys of ocean. Waving tendrils of kelp trap were spread everywhere except on the Maormer's own ships, and provided a well-camouflaged home for the sea serpents that served as guards and occasional mounts. Mist storms spilled over the land, further disorienting one's view.
The last documented appearance of the Maormer or Pyandonea was in 3E 110 in the War of the Isle. The storm brewed by the Psijic of Artaeum, it was said, annihilated Orgnum's fleet that he was never again able to muster together enough of a force to dare another battle. The mists to the south reveal nothing to corroborate or refute this belief, but one can hope.
