The Ceporah Tower is an ancient structure on the Isle of Artaeum, an island in the Summerset Archipelago. It is so old, it even predates the arrival of the Altmer on the island by several hundred years.[1]

The tower is used by the Psijics in some of their rituals[1], but is more famously 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.
