Wizards of the Coast have released a new module: The Head of Vecna ~ A D&D Adventure for Characters Levels 1-12 based on this story -> Original Inspiration
Synopsis: The PCs search for the head of Vecna, for whatever reason. They
are led by clues to a cave complex in the mountains north of Ket, where

the Head. There, they must choose a head and decide whether to attach it to a PC.
You have to be a D&D fan to get it of course.......
