The party attacks Orcwall with the help of soldiers of Wayrest, two of Sariel's fellow cultists friends, and Darmok & his pack of wolves. After the siege has begun and the party has pushed their way into the walls of the fort, a catapult breaks open the central tower, revealing a group of goblins opening up a magical portal. From the portal, Daedra pour out, attacking the Vosh Rakh as well as the party and their friends.
At the conclusion of the fight, the leader of the Vosh Rakh present surrenders to the party and willingly answers questions because of the aid against the betrayal of the Goblins.
The leader turns out to be one of Bakhutto's wives and she reveals a bit about Bakhutto's plans, especially a bit about her lack of understanding behind his motives.
