The player character of Aces is an unnamed Markovian Air Force pilot.
Their first “mission” was training to become a pilot. Their session was interrupted by Theolonius, who complimented their skill, before departing. Shortly after, the Aces defected from Markovia, and shot down the player. Either out of patriotism or for revenge, they began hunting down the Aces, starting with Theolonius, destroying his cult.
