Long ago, a magical war destroyed an empire, and a new one was built in its ashes. But still the old grudges simmer, and two siblings will fight on opposite sides to save their world.

Four hundred years ago, a cataclysmic war cracked the world open. Amid the ashes, the Dawn Republic now stands guard over lands littered with eldritch relics and cursed by plaguespawn outbreaks. But a new conflict is looming and brother and sister Gyre and Maya have found themselves on opposite sides of it.

At the age of five, Maya was taken by the Twilight Order and trained to be a centarch, wielding forbidden arcana to enforce the Dawn Republic's rule. On that day, her brother, Gyre, swore to destroy the Order that stole his sister... whatever the cost.

Twelve years later, brother and sister are two very different people: she is the Twilight Order's brightest prodigy; he is a thief, bandit and revolutionary. Together, the siblings will discover that not even ties of blood will keep them from splitting the world in two.
