Recap: After the Werewolf Battle for Volkihar, the Dawnguard hasn't trusted the werewolves. This leads to Ralph confessing his involvement in the battle and the deaths of many Vigilants. Geilir, the leader of the Dawnguard, sees the werewolves as a threat, while Corelas, his second in command, sees them as victims. Corelas leaves and creates a new faction called the Duskpatrol. The Duskpatrol lives with the Companions and Corelas learns that Ralph is slowly turning Feral. During Full Moon, the Duskpatrol and the Circle leave for Ysgramor's tomb, Romulus (The blood pack's Alpha) and Runa (of the Duskpatrol) battle, Ralph wanders off to the Reach, the Dawnguard get attacked by werewolves, and Ralph gives his just incase will to Geilir. This all ends in Corelas getting bitten by Aela, and a new member is being added to the Dawnguard's number.
