Marcos Xiorro was a Torch citizen and an officer of the Royal Torch Navy. Holding the rank of Lieutenant in 1922 PD, he was assigned to the frigate Denmark Vesey. During Operation Serket Breach, he was in command of the pinnace that boarded the slaving vessel Luigi Pirandello, and was proud to be the first Torch officer to liberate a group of slaves without the help of foreign powers. However, as soon as he and his Marines were aboard, the Luigi Pirandello, a Mesan Alignment agent activated the vessel's self destruct sequence, killing everyone aboard including Lieutenant Yiorro and his subordinates.
