Jeff LaSala is a production editor for Tor Books at the Macmillan Publishing Group, a freelance writer, and a longtime tabletop gamer. As a Tolkien columnist for Tor​.com, he writes essays that discuss, praise, and adoringly poke fun at all things Arda; for the Silmarillion Primer and its follow-up series, Deep Delvings into Middle-earth, he is entirely to blame. Jeff has written RPG adventures and campaign lore for Goodman Games, Dungeon and Dragon magazine articles for Wizards of the Coast, and the Eberron novel The Darkwood Mask. He can even be accused of hoodwinking a host of fantasy authors into writing cyberpunk fiction in the experimental, multimedia anthology known as Foreshadows: The Ghosts of Zero.
