- Complete the quest
The Vestige will be approached by Recruit Thomas, who will ask for help to find Captain Jerick. She will explain that their caravan was attacked, and that he was taken by Supernal Dreamers to their camp in Stormhaven during it.
After agreeing to help find the captain, head to the border and cross into Stormhaven. The camp will be located near Koeglin Village. Follow the marker to the right, then go to the large stone structure on the other side of the camp. Captain Jerick can be found being held by two braziers.
The Vestige must douse both of the braziers. Immediately after this is done, multiple Daedra, including several Banekin, will appear and attack. Once they are defeated, the portal will close. Once spoken to, Captain Jerick will explain that he needs to go to Koeglin Village to recover, and will ask the Vestige to meet him there in the Sleepy Sailor Inn. Once there, the Vestige will be rewarded and the quest will be completed.
