For good:
Rahlstein's creations/followers have been found wandering around, searching for items in which to free their master. These creatures must be found and hunted down, as they pose a threat. The items they carry must be confiscated and given to authorities to find out the means of how they were plotting to set Rahlstein free.
There could 4 kinds, or something, for good and evil. Neutral could have two good, two evil if they wish to take sides that way, or kill them all, not caring one way or another.
