Nowhere

Nowhere is a place beyond and above The Glory. From it dread drifts into the worlds bellow, and to it go all things that die. As both a place and a concept it is the very antithesis of creation, although some speculate it is the true source of all things.

"From nothing we came, and to nothing we will return" -unknown poet
Regardless of the truth to that theory; it is clear that the Worms have come from Nowhere and if left unchecked will reduce all things to Nowhere.
