- This page is about the actor. For the character from a one-shot campaign, see Taliesin Jaffe (character).
Taliesin Jaffe is a voice actor and director who plays the character of Caduceus Clay on Critical Role. He played Percival de Rolo in the first campaign, and originally Mollymauk Tealeaf in the second campaign. He was also the Storyteller for the two episode Vampire, the Masquerade mini campaign "Critical Role One-Shot: Thursday by Night" (Sx24) and "Critical Role One-Shot: Thursday by Night – Part 2" (Sx25). He was the Keeper of Arcane Lore for the "Call of Cthulhu: Shadow of the Crystal Palace" (Sx46) one-shot.
Taliesin's first role playing experience was the Generic Universal RolePlaying System (GURPS) in high school when he was thirteen years old. He also hosted a Rifts game, a World of Darkness game, Paranoia, and HoL: Human Occupied Landfill. He gave HoL core rulebooks to now-Dungeon Master Matthew Mercer for his birthday.
Before Mercer's Pathfinder-based Exandria campaign (which evolved into 5th edition-based Critical Role), fellow voice actor and player Marisha Ray and he were in another pen-and-paper RPG game together.
In the first session that Mercer's Exandria group played together, Taliesin played a dragonborn paladin. Because he was one of the more experienced players at the time, his purpose for that first game was to try to ensure that everyone else stayed alive.
When the players decided to continue playing past the first session, Taliesin created a new character and chose the gunslinger Pathfinder class because it was interesting to him and he felt it could fill a role that did not exist within the group.
When converting the campaign from Pathfinder to 5th edition Dungeons & Dragons in preparation for beginning the Critical Role livestreaming webseries, Matt had to create a custom martial archetype for the fighter class, since Percy was a gunslinger. Matt and Taliesin sat down together and spent a full day to convert the character and all of his stats and abilities.
He is often called the "Anti-Wheaton" by other members of the cast, as he rolls frequent critical successes.
During Percy's resurrection ritual in "Passed Through Fire" (1x69), Taliesin was watching from another room. After the ritual succeeded, Matt revealed that Taliesin was the one who ultimately decided if Percy would want to come back, depending on the actions of Vox Machina and their players during the ritual.
