He's coming back!
Acererak, that is, my favorite D&D villain of all time. A new Tomb of Horrors is coming out in July. The image above is not of Acererak, but rather of The Devourer, an idol associated with him. The Devourer is one of the deadliest traps in all of Dungeons & Dragons, probably responsible for more characters destroyed than any other single thing in the entire history of Dungeons & Dragons.
