(1 person) Simple escort mission. No guards near target.

You must first do the Kaja quests to get this far. The Inquisitor is directly inside the main hall to the left. The wall skillfully hides the door, but it will slide to the side when you enter. Soon as you pass the place you formerly couldn't because Kaja was being a pain, turn left, he's standing right there waiting to tell you what to do.

This gentleman will spawn when you accept this mission. Go talk to him and drag him back in for questioning, he'll come quietly.
