Thompson

 is a dwarf guard in the Carvers of Kraghammer. As an NPC, is played by Matthew Mercer.

Encounters with Vox Machina
Vox Machina encountered two Carvers as soon as they entered Kraghammer. When Tiberius asked about lodgings, Thompson misleadingly directed the outsiders to "The Pig Pits", which turned out to be actual pens for livestock. With a gold piece and a wink from Vex'ahlia, he directed them to more suitable lodgings in the Iron Hearth Tavern.

Later, Vax'ildan, Vex'ahlia, and Trinket tried to reconnoiter Greyspine Manor, but they caught the attention of some Carvers. To avoid conflict, they pretended to be sightseeing, and the guards escorted them to the Manor. The guards became scared of Trinket, so Vex sent him back to the tavern. On their way back to the tavern, Vax and Vex tried to ditch the guards escorting them. Vax vanished, but Vex was caught and flirted with the guard, Thompson, to divert attention from her brother. When Vox Machina encountered the Carvers the following day, Thompson was "noticeably absent" and, as one of the other dwarves pointedly remarked, "He's been given the day off."

Trivia

 * Matthew Mercer's first use of 's name sounded like Timpson, Timson, or Jepson due to the thick accent of the NPC dwarf speaking.  Later, Vex'ahlia enunciated Thompson's name as "Thompson", and the other dwarves did not dispute it.
 * The community-created CritRoleTranscript used "Jepson" when quoting Mercer and "Thompson" when quoting Laura Bailey's enunciation.
