Caston Gage

Caston Gage was a member of Meatbag Squadron. A survivor of a zerg attack on his home planet, he joined the Dominion Marine Corps out of a need for a revenge. While training at the abandoned Ghost Academy on Tarsonis, Caston killed a feral purple-eyed overlord, not knowing that it was an infested Gargantis Proximae, and one of the original overlords that joined the zerg centuries ago. The overlord's green-eyed mate (another infested Gargantis Proximae) took control of feral zerg, and targeted Meatbag Squadron, killing them one by one until only Caston remained. Realizing that he was responsible for the death of his friends and perpetuating a long cycle of revenge, Caston spared the overlord, and deserted the Dominon Marine Corps.
