Stefan in Ebon Watch asked you to go to the Reliquary of Agony to collect 5 Putrid Abomination Guts from the Putrid Abominations and 5 Gooey Ghoul Drools.
Once the Scourge have a target in their sights, they'll stop at nothing to acquire it.
You're doomed to a mindless existence as a walking corpse....
<Stefan's face twists into a cruel grin.>
... unless we can use their desires against them.
I'll explain later. I have complex magic to prepare which requires certain material components.
Travel due east of here to the Reliquary of Agony. Slay abominations and gather the ghoul drool you'll find there then return to me with their remnants.
