Sorcerer Vunal sent me into a deep vision with the help of an ancient ritual site. In this vision of the past, I should be able to interact with Balreth and Sadal. Then i can learn how the Brothers of Strife were born.
Collect Nedic Hearts
Collect Ornskar's Heart
Sorcerer Nilae wants me to cut out the hearts of Nedic warriors. They'll be used to power the upcoming ritual. Then I must kill their general, Ornskar.
Talk to Sorcerer Turoni
I've prepared the site for the ritual. Turoni instructed me to talk to Sorcerer Turoni when I was done with my task. She should be at the altar in the center of the ruin.
Collect the Essence of Fire
Collect the Essence of Wrath
Sorcerer Turoni asked me to kill two powerful Daedra, so I can harvest an Essence of Fire and Essence of Wrath from their corpses. I must speak with her acolytes at the nearby ruins to proceed.
Talk to Legate Sadal
The ritual preparation is complete. Talk to Legate Sadal and begin the final phase of the ritual.
Talk to General Balreth
Sadal told me the mages are ready to begin. I should speak to Balreth as the final step before the start of the ritual.
Place the Spirits in the Ritual Brazier
General Balreth has given me the honor of beginning the transformation ritual. I should pray at the Ritual Brazier to begin.
Talk to Sorcerer Vunal
I've returned from my vision of the past. I should talk to Sorcerer Vunal about what I've experienced.
