Arturia Melrose, an aasimari knight, is believed to have been summoned to Daria over 500 years ago. According to legend, she succumbed to her wounds shortly after repelling invading demon forces.
 
Her legend has endured multiple translations and iterations, as such, no two stories can agree on where he was summoned or how. The most popular telling indicates that she was summoned using a variation of the spell "find familiar". In most tellings of the tale, a desperate mother sacrifices her child in hopes of obtaining a more powerful fimiliar. Moved by her conviction the moon goddess procured a champion from another world to fight on their behalf.
