The comics that bridge the gaps between the Dragon Age games like Dragon Age: Those Who Speak take certain things for granted that aren’t necessarily canon in the player’s world state. The fact that Leliana returns in Inquisitioneven if killed in Origins suggests that Sten’s possible death in Origins is unlikely to impact his return in Dragon Age 4. Leliana can also be killed during the Urn of Sacred Ashes questline. It is possible to maintain a poor enough relationship with Sten in Origins that he attacks the player during the quest to find the Urn of Sacred Ashes.
Highlights include Sten growling back and forth with the Warden’s dog, and the deadpan dialogue he has with the player’s other companions throughout the game. Despite his dark backstory, once players free the Qunari, most are quick to warm to him.
Sten first appears in Lothering in Dragon Age: Origins, where he is being held in a cage after slaughtering a local family.
