Gaius served as Magister Qintara's valet for years. Upon the magister's death, Gaius impersonated him, using pyrotechnics to keep the illusion that he was still alive and experimenting within his estate. Gaius' true master is Fen'Harel, for whom he gathers information on the human world. After he obtained a weapon imbued with Red lyrium stolen from Kirkwall, he traded it away for information to House Danarius. According to writer Nunzio DeFilippis, this was not something Solas would have approved of.Gaius is slain by invading Qunari while trying to flee the Qintara estate.
- Gaius is not named in the comic, only in the "Early Character Sketches" section at the end of the collected edition. His name was first provided by writer Nunzio DeFilippis on the Unofficial BSN.
