Vinbarr’s Sanctuary Walkthrough
Head through the cave using the only route and kill various animals. Ultimately, you will find a point of transition to a new location. Go upstream and get to the islanders. Kill them all, including Cera, and then search her corpse. You’ll get -3 to reputation with the natives and find Cera`s seed. Move higher, examine the door and two altars. Put the seed for the mountain gates into one of them and seed of Cera to the other. The gates will open, and the quest will be completed.
