Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since.

When Alice Verianna went to sleep, she was just another teen from the Denver suburbs. She definitely didn't expect to be transported to a magical alternate dimension, inhabited by monsters and presided over by a mysterious System.

Now, after reaching the pinnacle of power, defeating the Void itself, and escaping the abyss, she has finally found her way back into the real world. But instead of returning to Earth, she arrives in the land of Vacuos. A fantasy world with magic, monsters, Classes, and Levels. A world that is governed by a System like it were a video game.

The Netherworld: it is a hellish landscape inhabited only by demons. Joining the ranks of newborn demons, Salvos is thrown into the violent, anarchy-ruled landscape of that world.

Every year, the empire administers the rite of passage into adulthood. That rite serves to identify those blessed by Aether to become magi. The new magi are shipped to the academy to learn the arts of magic. The academy is a dangerous place; the tournaments held twice each year can cripple or kill the students, and the clans of the empire will go to great lengths to recruit the students they want.
