Give the Sealed Note to Watcher Backus in Duskwood.
Jorgen, you ol' sonuva.... So, that's how it's going to be, huh?
All right, I can deal with that. I hope he finds the Twisting Nether that much sooner!
Here's what's gonna happen, [player]. I'll start using my contacts here, but you're doing most of the footwork so I save some coin.
Head to Darkshire in Duskwood and find Watcher Backus--he usually patrols the north road right outside of town. Just tell him you're looking into any Defias activity for me and he'll help you out with any information he can.
