Very little documentation has survived Aladris, except tangentially. However, it is know that Eastwatch was built by that empire as both a physical and metaphysical lighthouse of sorts. It is not known if it was built this way, but a sort of Oracle has taken up residence, an Angel, possibly a Deva. Many who have been are turned away by the Deva, and it will not speak with them. Those that were inside speak about the lighthouse almost changing shape to deter their progress, while some say they were never even able to find a door or window to gain entrance in the first place.
Some accounts speak of a silver-skinned Angel with Alabaster wings that spoke to them. Some instead say it was merely an elf with ancient eyes that seemed to see many places at once. Against all odds, there’s even one story that tells of a madman’s visit to the lighthouse told by hirelings afterwards. They all swear he received his pronouncements from a talking squirrel that spoke perfect Giant.
Some tales say that the supplicants have come back with gifts, though many come back with answers, both clear and confusing. However nearly everyone who goes comes back changed in powerful ways, even if subtle.
