Tyriok Gadsworth

is an apprentice cartographer, whom Vox Machina met in. As an NPC, he is played by Matthew Mercer.

Tyriok first met Vox Machina in Vasselheim, where they stopped in a tavern to ask for directions on their way to the Fire Ashari. He advised them to stay on the road for safety, and also requested that they take note of any landmarks or other information he could use for his maps.
