Jorgin is a Domani questioner who worked for Milisair Chadmar. He is overweight and seems to take some pride in his ability to do his job. When Nynaeve questions him, he is quick to tell her all he knows about the messenger Graendal sent claiming to be from Alsalam and is offended at the suggestion he killed him.
You think a man could get far in my profession if it were known that he'd accepted a bribe to kill one of his guests? You couldn't trust him any further than you could a lying Aiel" (To Nynaeve).
