Such a place no Man would wish to go, willingly at least. Beholders, Dark Elves, Illithids, Demons and the rest of the stereotypical "evil" beings. It was all relative and opinionated really. The Underdark was very diverse place ruled by the Elder Brain. The closest thing to a god the Illithids and higher Ulitharid nobles had. Imagine a mass collective of knowledge with a arsenal of Psiconic power. I would be here forever trying to explain some of the rumors about the Elder Brain. One thing was certain though, The Underdark was shielded by this said Brain.

And I was scheduled to meet "him" soon.
