Influential RPG adventure writer, artist, and video game creator Jennell Jaquays has died.

She was a founder of the Dungeoneer zine before it was sold to Judges Guild. Her D&D adventures Dark Tower and Caverns of Thracia became classics, often studied as examples of adventure design. She also wrote and illustrated for TSR, Metagaming, Steve Jackson Games, and many other publishers. Her video game career included developing many of Coleco's titles in the 1980s and level design for the Quake sequels at id Software in the 90s, and she co-founded the SMU Guildhall video game program.
