Four moons illuminate the sky in an alternate world governed by swords, magic, and monsters. This realm, known as Stellamund, transitioned from the tumultuous "Age of Tower" to the flourishing "Age of Crown." During the bygone era, wizards who ignited a catastrophic war have since lost their influence and now quietly delve into arcane studies at the Grimoire Academy. This narrative unfolds over three years, centering on an exceptionally gifted wizard born in this era, his female protégés, a relic from ancient times called the "Black Tower," where they reside, and the individuals drawn to them. The protagonist, Domino, earned the distinction of becoming the ninth preeminent wizard at Grimoire Academy. His rapid ascent in the wizarding world was unprecedented for one so young, yet he soon grew disillusioned with the academy. The other eminent wizards viewed magic merely as a ladder to personal gain, neglecting its research for power struggles. Seeking solitude, Domino relocated to the remote Black Tower, once inhabited by a legendary wizard from the Age of Tower. However, his peers disapproved and imposed a challenge upon him. This challenge was to mentor a fully competent wizard within three years—a feat typically spanning decades. Adding to the difficulty, his two wards, Aria Vancliff and Kaya Xavier, were among the academy's most challenging students. Will Domino be able to complete this difficult task...?
