Quintus Arterius

Quintus Arterius is the son of Castus Arterius and Teresa Kandros. Through his father he is the grandson of Quinteia Arterius, the infamous rebel biotic who became the first cabalist. Through his mother he is the grandson of Teres Kandros, first Primarch of Thracia, who fought at Aurelion's side during the Unification War. His father was killed by Aurelion when he was two years old and he has very few memories of him. His mother raised him on Thracia, in the household of her father. Quintus lived the typical life provincial nobility, never wanting for anything and receiving the best education.

When he was sixteen he was summoned to Palaven by Aurelion. Obeying his Imperator's command, Quintus and his mother journeyed to Cipritine and stood before his adoptive grandfather. Aurelion embraced Quintus and called him grandson, before handing him an imperial decree that granted him the right to wear Tyrian Purple, an act of formal acknowledgment of his imperial status. This was a great honour for Quintus and he cherished it dearly, always wearing purple on his person in some capacity from that day forth.

Aurelion briefly considered a match between Quintus and Cressida Aurix, one of his granddaughters through his illegitimate daughter, Flavia, but ultimately decided against it due to Quintus's marriage being a potentially volatile political issue. Unable to keep Quintus in the family or choose a colonial match without being accused of favouritism, he instead decreed that his grandson was free to marry whomever he desired, removing himself from the matter entirely in order to appear unbiased. Quintus chose to marry a Thracian woman, who was the daughter of his grandfather's Duarch. They had two children together; a son named Teres Arterius and a daughter named Tyra Arterius.

Quintus would be day become the Primarch of Thracia, following in his maternal grandfather's footsteps. As a man who was viewed as simultaneously Thracian by birth and Aurelian by upbringing, Quintus acted as a symbolic bridge between imperial and colonial culture, one which helped to foster a greater sense of understanding and acceptance between both groups. He worked tirelessly to bring Thracian concerns to the attention of Palaven's leadership, helping to heal much the scarring left behind by the Unification War. Regarding his paternal grandmother and namesake, Quinteia Arterius, Quintus spoke very little of her. What little he did say echoed his beliefs that his grandmother had been lead astray by a visceral fear of the unknown, which had empowered her to commit atrocities in the name of freedom, potentially suggesting that she had been mentally unstable. Despite this more understanding outlook, Quintus always condemned her use of biotics as a weapon of terror and supported the Cabals as an institution of mercy.
