Critical Role, a long-running Dungeons & Dragons web series, is a gem on the Internet, with loyal fans eagerly awaiting weekly updates to the group's running campaigns. While several guest appearances have occurred throughout the course of Critical Role, the main cast has largely remained the same over the years that the show has been going on, with one glaring exception. Orion Acaba, who played Tiberius Stormwind, departed from the show before finishing out the first campaign, while they were still a part of Geek & Sundry.
