Bring the Stolen Silver to Gazrog in the Crossroads.
You may have killed the raptors, but the silver they stole must be recovered! I have reports that the raptors have a large grouping of nests south of Ratchet, known as the Raptor Grounds. It is likely that they brought our stolen silver there.
Go to this raptor haven and search for the stolen silver. When you find it, return it to me.
