Ath Velanis

Ath Velanis is a fortress in Seheron. During the events of Dragon Age: Until We Sleep it is under the control of Magister Titus and his cult.

Background
When Ath Velanis was built, it was used by Malgorthios the Black in order to sacrifice women screaming to the Old Gods.

Centuries later, this fortress housed madmen, demons and the Fraternity of the Grinning Abomination.

Eventually, it fell into ruin until Aurelian Titus chose it as his headquarters. Except its very strong defences the fortress also serves as a place where prisoners are held as well as magical experiments take place.

Involvement
During the Until We Sleep the Qunari assault Ath Velanis with their new Arishok, Sten. Even if they are numerous and use their powerful cannons, they do not expect to capture the fortress but instead they try to buy time for Varric to slip into the castle undetected and release Maric Theirin while Alistair and Isabela confront the Magister.
