After the Coming of the Dark, most immortals in the world have been killed. The religion of the Four Tribes has taken over the world, and any who resist it are crushed. They await the return of their prophesised One, who is both male and female, and neither. They have not been seen for fifteen years, but belief rules all.
A few still fight. A handful of surviving immortals, once seen as gods, have hidden away. In each of the four lands of the world, there are mutterings of rebellion.
And over the mountains, kept secret from the world, the One has grown into their adulthood. It is time for them to return and see what is being done in their name. And that means going to war.
