Item Origins: Book of Vile Darkness (DnD 5th Edition DMG)
This tome is written in a shaky hand, on multiple types of humanoid flesh. It is dedicated to Mog Creoch. It is said to have appeared several times in hidden temples found to the dark force. It cannot survive direct exposure to sunlight and turns to dust – only to regenerate elsewhere, burried in the earth. The book itself is immune to rot and disease.
