Philia - Clemente
Back during the Ae'ther Wars, the commander of the group of people who were to become the Swordians was Laville Clemente. Certainly he was big and intimidating, and like Santa Claus, he was jovial and sometimes insightful. Unlike Santa Claus, he's also a perverted old man who's primary reason for choosing Philia to become his master was because she was a pretty young girl.
Although Clemente is fairly large, he has basically no attack power. Instead, he commands a repertoire of powerful magical spells of not only of his innate element, Lightning, but of every element.
Aside from that, Clemente is found underneath the ocean in the E'rther base, Radisrol.
