I have sent Orbaz, Thassarian and Koltira behind enemy lines to search for the courier. They have set up a base of operations at the Scarlet Tavern, located at the southern end of New Avalon. The tavern is tucked away behind the two orchards, adjacent to the Chapel of the Crimson Flame. You are to make your way to the tavern and report to Orbaz Bloodbane. He will update you on their situation.
Looks like we'll let anyone into the dark order these days. When I was given the gift, things were different. Much different!
As to this courier...
