Caius used to be a smuggler, one of the best, until he found religion. It was a sweet racket while it lasted, until the great god Grannus, a minor Celtic god who was one of Camulus's former lieutenants, got himself executed by his own Jaffa. Posing as Brother Caius at a monastery, he had known Vala as Sister Vesina when she was making her way as a trader, smuggler, and thief. Vala had stolen a necklace from Arlos, which she traded to Inago for a power coil from a cargo ship. As Sister Vesina, she had offered the power coil as a generous gift to Caius's monastery, where it became the legendary Ring of Shen-marak, a relic which pilgrims from all over the system traveled to see. Coincidentally, at the time of the donation, the shrine's most precious relic, the Livanna Crystal, had mysteriously disappeared, making it a bittersweet season at the shrine. Vala had also "borrowed" Caius's cargo ship, to which he had made a few special modifications, and the ship was now in the possession of the Lucian Alliance. When Vala and SG-1 sought help from Arlos to disengage the Kor Mak bracelets, Arlos demanded the return of his necklace, and Inago would only agree to cooperate if SG-1 returned his power coil in a straight swap, but Caius insisted that the pilgrims and their donations were the only thing keeping the shrine afloat, and the return of the priceless relic was out of the question. However, he had become desperate to escape the monastic life, the fasting, the chanting, the bathing the poor, the weaving of prayer baskets, and he was willing to make the trade if his cargo ship was returned to him. SG-1 had to recover the cargo ship from the Lucian Alliance, exchange the ship for the power coil, and trade the power coil to Inago for the necklace, which they then returned to Arlos.
