Task - Lost Comrades [68+]

Five days ago I sent a group of adventures into the Nest. Their mission was to explore the ice dragons' lair and recover a lost artifact known as the Orb of Midwinter. Only one adventurer has returned, and he arrived slumped over his horse, almost dead in his saddle. We do not know what has become of the rest of the group, but based upon the survivor's fevered whispers, we believe others may have also survived. Journey into the Nest and see if you can salvage this expedition. Find any survivors and then recover the Orb of Midwinter. The missing adventurers are named Varronghast, Dorsya, Kellendro and Gorvash. Good luck, my friend.
