Roommate. Pot thought he kidnapped him at first, but this got cleared up quickly. Still he hasn't really found it in himself to be super duper friendly with him for some reason. Maybe old habits; he is a king in his home world and his job required him to be respectful of royalty.
A swordsman with familiarity with magic. He seems to want to cover himself with a constant stream of nonsense, but he's seen him display real competence in battle and a caring streak.
Introduced himself as a lover of the arts, and so won Potemkin's favor very quickly. They have conversations over the challenges and questions that face an artist.
A powerful (and very chatty) warrior. Potemkin has been fairly charmed by him (and not in the magical spell sense). He's also royalty, but unlike Sion Potemkin tends to forget despite loud declarations of it. Maybe because.
Extremely loud (Potemkin has literally never not seen him yelling) and cantankerous. Calls him 'bucket of bolts', a nickname picked up during their mostly one-sided rapport on a Blanc warship.
Having worked together on various jobs in Blanc, especially warfare related, Potemkin sees Levi as someone to get things done. They are a naturally coordinated team as they seem to have similar priorities.
