In the broken world of Remnant, a shadow war that has lasted for thousands of years rages on. But when mysterious spirits begin arriving on the planet's surface, the world and it's people must confront the truth about their genesis and the plot of the forces who brought about it.

11 years before Ruby Rose and her friends were dragged into a war for Remnant's fate, strange people with powers beyond any semblance begin arriving on the planet. For Ozpin and his allies, it meant facing enemies more dangerous than anything they have ever seen. For Percy Jackson and his friends, it meant fighting one last war in a world they did not belong in.
