Peter Chenoweth

A writer at TSR, Inc., publisher of Dungeons & Dragons, Peter helped draft the Dungeon Master Guide. Specifically, Chenoweth suggested adding the Baba Yaga legend into the guide. He was also an expert in Slavic folktales. After the guide was published, Chenoweth went for a vacation in the woods in the Pacific Northwest where he disappeared. He returned three months later, dazed and confused, and thinking that only an hour had passed since his disappearance. A week after his return, Chenoweth hung himself.
