Yig Snake Grandaddy – Lead Developer

Jonah Bomgaars is a medieval historian and an avid worldbuilder and game designer. He has been playing tabletop RPGs for 12 years and GMing for almost as long. In 2013, he started releasing Open Game content and GMing advice on his blog at d20despot.com.

He channeled his lifelong fascination with prehistory into the writing of Petersen Games’ Yig Snake Granddaddy, which is also his first time as lead designer on a published adventure.

Jonah lives in Seattle with his wife, Olivia, and their cat, Ishtar.
