Additional lore on Ser Zephirin was given in a Dengeki Online Interview, which mentions his great sword:
Quote:Ser Zephirin the Valorous (lit. “of the righteous heartâ€)
Lord Commander of the Heavens’ Ward; originally Commander of the Temple Knights. To compensate for his naturally slender frame, he wields a massive sword — a weapon not usually favored in Ishgard because of the reputation of the dark knights, but Zephirin is the sort of man who ignores the rabble to do what he believes is most just. Despite being a candidate for Lord Commander of the Temple Knights, he unexpectedly lost his seat to Aymeric… but Ser Vellguine saw potential in Zephirin’s honesty, skill, and cautiousness, and requested that he become the leader of the Heavens’ Ward.
