Ganofus asked you to fight the commanders of the Zorshiv Dredgion leading the efforts to reconquer Sarpan. So you went to Dredgion incursion zones in the Kamar Outskirts, Dredgion Bombing Area, Ruined Jotun Citadel, and Satrakand with your fellow Daevas. After killing the four commanders, Ganofus sang your praises and rewarded you handsomely.
