Wilderlands Age of Worms
Talabir Welik is an employee of the Arena in Tula. Among other things, he serves as referee of the Champion’s Games. Talabir is concerned primarily with making sure the games themselves run smoothly. It appears, from his initial speech at the opening banquet, that he takes his responsibility as referee of the Champion’s Games very seriously, and plans to follow the rules literally.
So it turns out Talabir was not mixed up in the Ulgurstasta plot. The “among other things” up there was just a red herring that the party didn’t really get too concerned about.
