- "He used to be a smuggler. One of the best I ever knew. Then things got a little too hot for him, and he had to find religion."
- ―Vala Mal Doran
Caius was a former smuggler and one of the best Vala Mal Doran ever knew. He was traveling in a Tel'tak he modified himself, which he used as a cargo ship. When things got a little too hot for him, he went to be a monk at Grannus' monastery. At the time when Vala, together with Dr. Daniel Jackson and Lt. Colonel Cameron Mitchell, met up with him at the monastery searching for an item called the Ring of Shen Marak he demanded that they, before they could receive this ring (really a power coil), get back with his cargo ship.
