You were raised on Mindoir on the fringes of the Attican Traverse. When you were sixteen, the colony was raided by slavers. The entire settlement was razed and your friends and family were slaughtered. A passing Alliance patrol rescued you, but all you loved was destroyed.
You enlisted with the Alliance military and were posted at Elysium. You were there during the Skyllian Blitz, an attack on the colony by a massive coalition force of slavers, crime syndicates, and batarian warlords.
You rallied the civilian inhabitants, leading them in their desperate fight to hold off the invaders. When enemy troops broke through the colony's defenses, you single-handedly held them off and sealed the breach.
After hours of brutal fighting, reinforcements finally arrived and the enemy broke ranks and fled. Because of your actions, Elysium was saved, and you are regarded throughout the Alliance as a true hero.
