Casey Nolan was a MechWarrior serving during the FedCom Civil War on the side of the Federated Suns. He first served Sir Peter Dresari, and then Lieutenant Ian Dresari on Kentares IV and the planet's moon Columbia. Became quickly Ian's best friend. After Kentares was freed, he was awarded a position of command at a school for elite MechWarriors on Kentares, which was a symbol of the heroic deeds of Ian Dresari during the guerrilla battles in the Kentares system. The school was attacked by a single MechWarrior, Eric McClair, who killed Casey in battle. Casey was known for often joking on the comm, which either disturbed or amused his lancemates.
