Krix

 was a chain devil jailer in the prison of Mentiri. As an NPC, is played by Matthew Mercer.

Appearance
Krix was a towering chain devil with broad shoulders almost as wide as Grog’s, and a head so deeply set within the neck that it almost gave a profile from shoulder to shoulder of a square.

Krix tried to scare Vox Machina using their chains but was interrupted by Ipkesh's agent.
