Decimus

Decimus is a character featured in Dragon Age II.

Background
Not much is known about Decimus's past. He used to be a mage at Starkhaven before it burned down. Some other mages in his group suspect that he is the one who caused the fire.

Involvement
Decimus is involved in the quest Act of Mercy. Ser Thrask will send Hawke a letter asking him to come to a remote cave along The Wounded Coast. When Hawke arrives, Thrask will tell him that a group of apostate mages who escaped from Starkhaven are hiding inside. Hawke must get them to surrender or else Ser Kassar will arrive and slaughter them. After entering the cave and eliminating the early threats, Hawke will find the apostates at the back of the cave. The group is lead by a man named Decimus. Decimus has taken up blood magic and is ready to fight to the death for their freedom. Hawke kills Decimus and the few mages that fight by his side.

Result
Decimus is killed and so are some of his mages. However, a few mages are not killed and are convinced by Hawke to flee. Unfortunately, most are recaptured and sent to The Gallows. Alain says that some were turned Tranquil.
