What is it? Is there any info on it?
It is called the Scuttling Void
Is anything known about it?
No. Based of the name of the place and the Daedric Lord who lords over it I would think it is a horrible place no man or women would want to be in.
Oh you mean like 3\4 of all Oblivion planes? lol
You mean "repulsive."
Honestly, Namira seems to be the worst of the Daedric Princes.
