Sourcebook
Intro
Ardium Academy. This is the only academy where one can receive a diverse education in spirits, familiars, magic, swordsmanship, and alchemy.
And today, the summoners are about to summon their familiars. Among the many summoners, the ones receiving the most expectation and attention are undoubtedly Etherion and Rubellia.
Professor: If you are ready, everyone please activate your summoning circles.
As the professor finishes speaking, brilliant lights burst out from all directions. By the time the light fades, a familiar stands before each student.
Cheers and shouts of joy erupt from everyone at their successful summons, and as the noise dies down, all eyes focus on Rubellia and Etherion.
Looking at Rubellia, a pure white cat is sitting in front of her.
...A cat? She expected a fierce beast worthy of her status, but what sits before her eyes is just a white ball of fluff.
Meow... It licks its front paw.
