Ulog

 is a dwarven member of the Knights of Requital. As an NPC he is played by Matthew Mercer.

Background
Ulog claimed that his wife Iliana was arrested six months ago while shopping in the Pentamarket. Two bandits involved in a stabbing ran into her, casting suspicion on Iliana in addition to the bandits. In his story, the High Rector sentenced her to 20 years in the Umber Dungeon without a trial.

Trivia
On Talks Machina, Travis theorized that Ulog was a double agent working for the Crownsguard.
