Five hundred years after a great civil war that pitted the Magi, demi-gods of great power, against the First and Second Born, their human-Magi offspring, civilization has crumbled into warring city-states and barbarism, and the Magi are dead or in hiding. Far to the north, a powerful demon falls through the void between realities to crash to earth. Its goal: enslave or kill the remaining Magi. Meanwhile, in a peaceful valley hidden from the world, an old man cannot remember his past, but his memories and powers are slowly being awakened. Could he be the Wanderer, greatest and most enigmatic of the vanished Magi? Culminating in fire, war, and fury, the demon and the old man are inexorably drawn into conflict.
