Liam O'Brien

Liam O'Brien (@VoiceOfOBrien) is a voice actor and plays the character Vax'ildan in Critical Role.

This is Liam's first "pure" game of D&D. Before this he was a Dungeon Master in his sophomore year of high school as well as a player, which, as he states, "is totaly cheating." He also ran a Rift game as well as a Cyberpunk game. He is currently running a D&D game for his 8 year old son.

Liam was indirectly responsible for starting the Pathfinder game that would later become Critical Role. He was the director for Matthew Mercer in Resident Evil 6, a video game. Matthew kept telling Liam about how he was running a D&D game, and kept inviting Liam to join. Eventually for Liam's birthday, he and Sam Riegel along with a few friends played a game of Pathfinder with Matt as Game Master. He enjoyed the game so much he messaged everybody, asking if they would like to start a continuing game. They have been playing since then.

Towards the end of episode 2 of the pod cast allworknoplay, Liam and Sam Riegel talk about getting ready for the upcoming "one-time" D&D game
 * You can find the first episode here.
 * You can find the other episodes here.

Liam and Laura Bailey play the twins Vax'ildan and Vex'ahlia (respectively) in the game because they both share the same birthday.

Prior to streaming their D&D game, Liam would record snippets of their game play back when it was being run with the Pathfinder RPG system. He still records some behind the scenes footage of Critical Role which can be found here.

When asked if he could switch to any player character in the game, Laim said Scanlan.
