The Warden is to determine the status of the conscripts of Company Easthill, and report back to the Chantry.
After receiving the quest, a new location will be added to the World Map, marked as Battlefield. Travel to the location to find several bodies laying around. The Bloody Corpse closer to the Warden's entrance yields a Soldier's Diary as loot.
The field holds other Containers (specifically, Sacks, as well as some herbs), and at least one more Bloody Corpse. As the Warden approaches these goodies, a pack of wolves will attack.
Note: The number of wolves may vary, see the Discussion page for details. however, it seems there are 2 waves of wolves triggered as the Warden approaches different containers.
A third attack comes in the form of a single Bear (again, triggered by approaching another Container in the area).
Eventually, all the enemies are dead and the loot picked up. Return to the Chantry representative in Redcliffe Village for your reward.
