Dialogue
 * The Priests of Balthazar are quite upset, it seems. They sense grave danger on the horizon, and while we have sensed this as well, we do not feel that crushing the spirit of the local population is the best way to prepare. Of course, the Priests of Balthazar have been less than receptive of our alternate solutions.
 * Against our better judgement, we have agreed to meet them in battle with all the forces we can muster, so we can show the residents of Tyria once and for all that, with hope and camaraderie, we can survive anything. If you wish to serve Dwayna and Melandru, speak with Melandru's Watcher. Should you wish to join forces with Grenth and Balthazar, you should speak with the Champion of Balthazar. Both can be found in either the Temple of the Ages or the Chantry of Secrets.
