“Tranquility”: In search of Deep Roads maps, Hawke and her companions meet Anders, a former Grey Warden who ran a clinic in Darktown. He’s in hiding because he’s a bloody mage.
In exchange for the maps, Anders asks for help with freeing a mage friend of his. Anders originally came to Kirkwall to finish this task.
His friend, Karl Thekla, was imprisoned in the Gallows. But by the time we reached the Chantry, Karl was already a Tranquil. Then, some Templars came to kill us, but Anders used some sort of frightening power to help us fend them off. This power, derived from the Fade, brought Karl back from being Tranquil, but only for a time. He begged Anders to kill him. Ilyria tried to talk Anders out of it, but he couldn’t stand to have a friend made Tranquil.
He said goodbye one last time before he stabbed Karl.
