Detention Camp Warden:
Enter the fortress dungeon and slay the prisoners you find there.

Your task will be to eliminate the 3 groups so that the remaining evil creatures in the camp can be driven out. Kill the General Monster of the
last group, and bring back the Dungeon Leader Badge.
In return, I'll give you the Knight's Epaulette, which you can use to exchange the clan's supplies from a supply general.
Ah, one last thing...
the prisoner leaders we've identified so far are Brand the Exile, Commander Koenig and Gerg the Hunter.
I can grant you access to the fortress dungeon camp.
Good hunting!
