Profile
12F was the alias commonly used by this Operator in his mercenary work. By his own account, he vacillated between different factions and was involved in several famous battles over the past few years.
The few verifiable documents we have confirmed that 12F was indeed present for these conflicts, either as a regular mercenary or security for a local facility.
He joined Rhodes Island with Owl, having been admitted for his unique combat experience as well as his experience in general. Now a standard Arts Operator assigned to normal duty.

Originium Arts Assessment:
Despite his extensive combat experience, 12F's Originium Arts was not decisive in any of his battles, as his own accounts confirm. But his grasp of Originium Arts is slightly better than your typical caster, and maybe factor into his continued survival.
Archive File 2
12F appears very stern and abrasive, but feedback from most Operators who have worked with this inconspicuous caster has been positive. The comments include 'Didn't hold up the squad,' 'helped smooth over internal conflicts,' 'provided timely assistance,' 'made unexpectedly good suggestions.'
Archive File 3
12F gets along with many Operators. In contrast, his closest friend, Operator Owl, has few other friends at Rhodes Island. 12F often makes concerted efforts to speak to Owl at places she frequents. Because the medical department is too busy to keep up on Owl's state of mind, 12F has been providing regular reports.
Archive File 4
12F has described many of his battles in detail, but reports that he's forgotten what his home and family looked like. '12F' was the designation he was given for his first mission. That was when he met Owl, who was on the opposing side. He was gravely wounded but lived long enough to become a prisoner of war.
