Luminous was just a "normal" fifteen-year-old lady in waiting (you know if you consider the fact of not only being the one blonde in the entire nation but also her strange imaginative theories about other worlds normal.) for the red prince (who was supposed to be the next queen of castle red, but to his mothers dismay was born a boy), when one day these creatures called "The Corrupt", take siege of the castle. The only one left it seems from the attack is her strange "librarian" named Master Mouse, as you guess is a small mouse (who I think is more than what he tells us.) He leads her to this magical archive, where he keeps a magical talking sword called the Dawn of Fate(an old gruff sharp tongue sword.) She is told she has to defeat the corrupt and the current crow king to save her kingdom, her best (and well let's face it really only) friend the red prince, and her crush (the stoic) knight in training, Chasm. With nothing but determination, her sharp tongue enchanted sword, and a snobbish cold in all meaning of the word nine-year-old boy prodigy ice wizard Vainglorious.......and you know all the other enemies they have to fight along the way.
