The Demon Lord is dead. The System is broken. Somehow, Elias Hearthsong is neither of these things, despite being at the final battle of the Demon Wars. He is a Master Enchanter, perhaps the last one alive. Determined to keep a promise, he crosses the continent to protect his dead friend's legacy: a crumbling orphanage run by a beautiful kitsune. He isn't a teacher, nor does he have experience with children. But with the love of a few good women, anything can become possible.

Life sucks. Gabe Harris has been clued into this fact for a long time now. In his mid-twenties, life has been nothing but low paying jobs, petty power-tripping bosses, and the worst roommates mankind has to offer. Bills, debt, and misery have haunted him for his entire adult life and, to make matters worse, it feels like his dream of being a writer is dead on arrival. One fateful night, he decides to take control of his life and make his dream a reality.

Located at the Edge of the World, this prison carries a secret. Those inmates who have magical abilities are trained in the most powerful magic known to the empire: battle magic. To survive, I will need to discover a secret I didn't know I possessed. I can become more powerful through bonding with the other beautiful, magically inclined inmates.

The last thing I expected was to gain the spells of the woman in my bed. Hell, I didn't even know magic existed until I'd cast a spell that morning. Then a beautiful teacher from a magical academy told me I could become the universe's most powerful mage. To get there, I need to become stronger. I need to ace all my examinations. And, most of all, I need to master the most potent spells. But I have to start somewhere.
