The Milities Empire's capital is Ingram where the White Peristylium, an organization that conducts research into the energy from the Byakko crystal, is located. Different from the crystals of other countries, whose power can be wielded only by a select few like the students of the Vermilion Peristylium, the power of the Byakko crystal is used to create weapons and Magitek for both military and domestic affairs. When the Miltesi Emperor had gone missing, Cid Aulstyne takes over all government affairs as well as the White Peristylium. Cid then used the Militesi government to break the Pax Codex and sparked a war between the nations by invading Rubrum to obtain the Vermilion Bird Crystal.
