Critical Role Productions
Brennan is credited as Special Thanks in Explorer's Guide to Wildemount for playtesting the Hollow One supernatural gift with his character Deadeye on Not Another D&D Podcast, a year before it was published in the book.

He played in. The blue dice bag he used during the game (seen in the photograph above) was one he's owned since he was ten. It was nearby when he watched the Campaign One finale,, which aired before he ever played D&D before a camera. He felt it meaningful to be able to bring the bag with him to a Critical Role table.
