The Great Omanderie Festival indeed sounded like a great opportunity to the Swordmaidens.
Back when they were known as Lydia's Swordmaidens, they used to number hundreds of mech pilots. They had grown into a formidable outfit in their own right in the Faris Star Region.
Sadly, numerous battles caused their ranks of active mech pilots to dwindle to a single mech company. The catastrophe that took place on Aeon Corona VII was the most devastating moment in their history.
They should have laid low for a few years in order to restore their lost strength. Yet what happened to them afterwards only led to further losses.
Their lack of external recruitment made it so that they had never been able to gain enough time to replenish their ranks before they were thrown into yet another dangerous battle.
