This is Garr Kelvin's Swordian. The personality written inside the weapon is that of Igtenos Minarde, leader of the E'rther Army's Intelligence Unit from the Aeth'er Wars.
After the Aeth'er Wars, he became a symbol of the royal house of Phandaria, handed down from one king to the next. He is calm and controlled, and prides himself on his logical decision making. He is deactivated due to the forced usage by Lydon.
He controls wind-based spells, but is also melee-focused, balanced between Dymlos Timbre and Pierre de Chaltier in power and speed (focused on stabbing, like Atwight Eks).
