Garthok

 is a member of the Clasp encountered by Vox Machina in. He is played by special guest Jason Charles Miller.

Encounter with Vox Machina
As Vox Machina travelled from Greyskull Keep to Gilmore's Glorious Goods after the Chroma Conclave's attack on Emon, they noticed a dark figure approaching them. The large half-orc, recognizing the group, communicated his purpose using the convoluted and coded Thieves' Cant, which Vax'ildan and Vex'ahlia understood. He then introduced himself as Garthok, a member of the thieves' guild.

Garthok joined Vox Machina as they stealthily made their way through the devastated streets of Emon. When the group found Gilmore's Glorious Goods in the process of being looted by citizens seeking to ally with Thordak, Garthok aided Vox Machina in defeating the looters.

Upon finding Gilmore and the survivors of the Tal'Dorei royal family, part of the group led the survivors back to Greyskull Keep while Garthok and the others headed toward a secret Clasp entrance. Garthok briefly tried to help the group recover some of Gilmore's stolen treasures, but the loot was already gone, so Garthok returned to the Clasp's tunnels to find his colleagues.

Vox Machina briefly see Garthok amongst the members of The Clasp when they meet with Spireling Shen. When Vox Machina reject Shen's deal they are marked as enemies of The Clasp and told to leave. When Scanlan tries to talk to Garthok he refuses to respond or acknowledge Scanlan; his place is amongst the Clasp and they are now meant to be enemies.
