Orionis commands military forces for the Brazilian Empire. He is the commander of the airship *Holmain Tzwicke* and leads a fleet to conquer the missionary city of Kerutoria.

In the midst of the operation, he intercepts communications detailing the rogue general Elmedine’s destructive actions at Las Katas Castle. Orionis personally leads the assault on the city, launching from his airship to command a ground attack group of Woodsman tanks.

His forces are decisively defeated in combat by the sentient combat armor Shaian and its new operator. After this military setback, Orionis’s surviving airships withdraw from the engagement to deliver a report to Elmedine.
