Bermund reveals that the Worm Cult is actually in Vernim Woods, and they're doing something to the Reachmen. You should talk to Dajaheel and the Centurion if you want to help.
Dajaheel is in one of the tents. They've tried everything to figure out why the Reachmen and the Worm Cultists are here. An undercover agent, Belron, has proposed two options: cut out a cultist's heart with a magical dagger then reanimate him or her, or use a globe to collect the cultists' memories. You can choose which one you want to do.
After you find the information, talk to Lieutenant Belron who is across from the tents. The Reachmen made a deal with the cultists. The cultists reanimated Sinmur, in exchange for a blessing from the Lord of Brutality. Stral himself is undergoing this ritual right now in the central ruin.
Report to Dajaheel with the information. She'll send troops to investigate the ruin, but she gives a reward for your work.
