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.

Tyriok met the party second time when they were traveling through Frostweald to find Kamaljiori. He had been traveling all over Tal'Dorei with two companions when they were attacked by basilisks and turnd to stone. Fortunatly Vox Machina passed near the place were Tyriok was attacked. Party defeated same basilisks and turn Tyriok back to normal. Sadly he lost his hand and all of the research because his hand wasn't attached when hi got turned back to normal.
