Taking place sometime after Darius II, Proco and Tiat realized just how far Belser had reached into space and hurried back to Orga in hopes of warning the populace. The time they were gone was just enough time for Belser's allies to regroup and spread beyond Darius and begin their invasion of Orga. Once again, Proco and Tiat are quick to throw themselves into battle.
