Walkthrough

"What are you doing here? Intruders!"

―Warden Cornexius

The Vestige lands in a village of Soul Shriven and must find a way into the castle when they meet Cadwell. They enter through the Cistern and make their way to Abnur Tharn through the Tower of Bones, after defeating the Corpse Tearer boss. On the way, the Vestige may have to fight several Flesh Atronachs and Dremora. Tharn guides the Vestige in creating a Runty Flesh Atronach to destroy the tower door's barrier, will sear the Vestige and inflict 10k damage if touched. The various parts needed to make the atronach are located throughout the area, with two near the Haunter of the Cliffs.

Tharn tells the Vestige and Lyris Titanborn about Mannimarco's plan to become more powerful than Molag Bal and even replace him as a Daedric Prince, by trapping Molag Bal's essence with the Amulet of Kings and absorb his power, before they get interrupted by Mannimarco himself.

At first, Mannimarco will summon four skeletons twice. When the Vestige has defeated them, Mannimarco will summon a Bone Colossus boss with four more skeletons. 

When the Vestige has defeated Mannimarco, they will have to flee back to The Harborage through the Tower Summit where they'll meet Cadwell. The Vestige can choose to bring Cadwell back to Tamriel or let him stay in Coldharbour.

Back in Coldharbour, Tharn reveals that he doesn't know where Sahan is, only that Sahan is Mannimarco's prisoner. Lyris punches him, and the true identity of The Prophet is revealed.
