Vequa and I are here to help.

Unit Lore
One of the legendary Battle Maidens, Serin was a noblewoman with the soul of a warrior. Finding an unbreakable bond of comradeship among her sisters-in-arms, they sought to overcome impossible odds and topple the callous gods of Grand Gaia.

Their victory over their divine adversaries was hard-won, as every Maiden carried on to the bitter end. Serin was the voice of command for her sisters, coordinating their attacks and providing covering fire with her powerful gatling gun, Vequa. Her bullets tore through the enemy ranks, bringing down torrential hell on their adversaries and wiping their vile influence from the land.

Even the unlimited might of the gods could not stand against the combined assault of the Battle Maidens. When the war was finally over, Serin felt an incredible wave of emotion sweep over her in the form of cathartic tears.

The Maidens were hailed as heroes by the people of Grand Gaia. Serin, who possessed both sublime beauty and tactical leadership, received many suitors seeking her hand in marriage. She rejected them all, cryptically stating she was "married to her job." To this day, no one has questioned what kind of job requires a giant gatling gun and a flock of top-hat wearing ducks.

Serin remained in Grand Gaia, giving counsel to the nobility and the military when approached. High society seemed to fit her well, but she preferred a more spartan lifestyle—a remembrance of the time she spent with her sisters.
Trivia, Additional Information & Notes
  • Serin's skills and title can be translated as:
    • Mitrailleur is French for Gunner
    • Tourbillon is French for Whirlpool
    • Maîtresse is French for Mistress
    • Sangfroid is French for Cold-blooded
