Calson was a Human male trainee starfighter pilot who was under the command of Ranna Gorjaye at some point during the Galactic Civil War. During a training patrol over a planet, Calson crowded the formation and clipped the wing of Gorjaye's fighter, sending both craft crashing into an area known as the Wilds. On the ground, Gorjaye ordered him to fall in line and follow her to a nearby settlement, but Calson refused to take orders from a woman. Setting out on his own, he was killed by a corvaj, a predator native to the Wilds.
