Walkthrough
Southwest of Grazden the Protector near Sardelac Sanitarium you'll find a NPC named Thaddiel amongst the ruins. Talk to him and convince him to stop scavenging. Return to Warmaster Tydus for your reward.

Talking to Thaddiel is a bit of a logic puzzle. There are several paths through the conversation, most of which accomplish nothing or loop around. The proper sequence to get him to leave is "What are you doing here?", "I have orders to clear the area of Scavengers", and "Only if you make yourself useful."
