Charlotte Meklen had crossed into the Fars Empire, seeking only to become a civil servant in a different continent. She wasn't a combatant... But who would have thought that even clerical staff would end up on the battlefield!
Charles, Krel, Ebner, and the Army of the Black Phoenix had a fierce battle, each suffering losses, Fars had lost a Sacred Order and annihilated a Knighthood, while the Army of the Black Phoenix had nearly lost the majority of its forces. Neither side initiated a second battle.
Because the Army of the Black Phoenix no longer had common soldiers, it couldn't hold the frontline and could only slowly retreat.
Charles had originally wanted to separate from the Army of the Black Phoenix and retreat back to Behemoth, but Kreel Brittany could not allow himself to retreat so easily and insisted on persistently pressing forward. Charles eventually had no choice but to reluctantly compromise. After the three Knighthoods re-entered the South Seraph Region, they found that the situation was both much better and much worse than they had anticipated.
