Marion Cailus

Marion Cailus is the Kabalim Primus of Taetrus, the planet's foremost authority on biotic acclimation and training. Once a cabalist of the Talae Cabal, he is a childhood friend of Desolas Arterius II and the husband of Eulia Valen, with whom he has a daughter. He works closely with his wife's grandfather, Primarch Idus Valen, to promote tolerance and the safe integration of biotic individuals into wider Taetrian society.

Biography
Marion was born in Cipritine in 2152 CE. His father was a dockworker and his mother was a customs officer, both of whom worked at Cipritine's Interstellar Spaceport. His mother was exposed to element zero while pregnant after a troop transport crash at the spaceport; the same crash that an unknowingly pregnant Maea Abrudas was involved also in.

Marion was never trained to be a kabalim. The role was expectedly thrust upon him after the death Alasius Carteia and the transfer of his protégé, Desolas Arterius II, to the Human Systems Alliance following the massacre at Akuze. As they were the only surviving members of the Talae, Marion promoted Eulia Valen to be his optio. For a long time, their cabal consisted of just the pair of them. Marion's first act as kabalim would be to oversee the burial of Alasius within the Talae vault after the previous kabalim's remains were shipped back home.

Despite his wise-guy attitude and somewhat impertinent nature, Marion did train hard to improve his biotic abilities. He eventually learned how to cast an aegis in the same fashion that Alasius once had. He used this ability to repel a charging brute during the Final Push, saving the life of Idus Valen, the Primarch of Taetrus and grandfather of Eulia. His courage in the face of certain death earned him a medal for valour - the first medal awarded to an active cabalist in turian history. Idus would later promote Marion to the rank of Kabalim Primus following Taetrus' declaration of independence from the Turian Empire, granting him absolute jurisdiction over the training and welfare of all Taetrian biotics. Along with the rest of the Taetrian biotics, he was also granted the right to reclaim his family name, marry and sire children, total freedom of movement, and wear the colonial markings of Taetrus.

Marion took full advantage of all his newfound freedoms. He wed Eulia soon after the war and the pair set about training the next generation of Taetrian biotics together, now that they were free from the proverbial shackles of the Dicasterum Mutarius. Eulia would give birth to his daughter, Alasia Cailus, whom they named in honour of their old kabalim.

Marion is a designated parrigogus to three of Desolas' children - Janus, Sarena, and Cassian Arterius. Desolas granted him the honour in recognition of Marion as his best friend, as well as the fact Marion's wife had been the female donor for the conception of all three children.
