Grima!Loustica, my Fire Emblem Awakening MU in the "Future Past Timeline" UWU/
I might change the colors/some details when I'll do her proper character sheet, but here's the main design idea!
Story:
That Lou is the one from Adult!Lucina's timeline.
She was raised by Valldar/Validar to become Grima, corrupted since her birth.
Her father told Loustica to kill the Exalt, Prince Chrom, in order to steal the Falchion, as he knows it's the only way to defeat Grima.
Her tactic to fulfill this mission is to "act" as a simple mercenary, setting up the fight in the village with the brigands (the one from the beginning of the game), so she could proove herself as an ally to Chrom.
Killing him would be much easier that way.
