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.

The decision to start a new life is never an easy one, but for Joe the transition was far from figurative.

Every year, the empire administers the rite of passage into adulthood. That rite serves to identify those blessed by Aether to become magi.

The gods should have agreed to fight the giants and let Ragnarök run its course and bring about the end of time. For a new world could only rise from the ashes of the old.

And so I was born. One of the many seeds dispersed by the mighty World Tree, I was teleported through different planes and universes to find a new home where to settle.

When Aesca Lampi wakes up in the form of her character from Eldest Fantasy Wars Online, she's annoyed by the historical inaccuracies. (Video-game-style scrolls? Really?) That is, until a building collapses on top of her, revealing she's on a fantastical island centered around the impossibly tall, glowing Tower of Aetherius . . . with an array of dangerous creatures—including jaguar hybrids, velociraptors, and giant, flesh-eating lizards—in the way. (Oh, joy.)

On Ludus, life is often cheap. Nora's childhood hadn't given her many options. With nowhere else to go after losing her family, she joined an old friend in a street gang and found an unlikely home there. But unfortunately, tragedy is about to befall Nora.

Nature is dying. Perhaps before the world is turned into an industrious machine, nature itself can play one final trump card to save itself. Summoned to a new world, a mushroom-loving mycologist needs to grow up and grow stronger in order to accomplish the goal that brought them to this new place: to save nature from the system that the sentient races have created.
