Setting the Wards: The Lower Cathedral

Overview
You must find 3 altars and purify them in an attempt to stop the undead from overrunning the catacombs. When you enter the quest, you'll find a resurrection shrine and a rest shrine engulfed in a bright glowing field. This field will instantly destory any undead that touch it, but other creatures can walk freely through it. Leading the more powerful undead back to this area is a good way to get rid of them. Note, though, that undead with ranged attacks can still freely fire into the aura, they just can not walk into it, themselves.
