Shade Perilous is a lightless place of Evergloam. It is one of seven strongholds Nocturnal possesses, as well was one of the realms that can be accessed from the Battlespire.
Description[]
It is a place in which no light resides or shall enter. Supposedly, Ebonmere is the main way to enter and exit Nocturnal's realm, and it can only be unlocked and locked by use of the Skeleton Key.
Creatures[]
Nocturnal and many lesser daedra, such as Seducers, reside here.
