Description:
Many years ago, the powerful Sartan ended a war by sundering the world into four elemental worlds -- sky, fire, stone, and water --, and imprisoned their enemies, the Patryns, in a labyrinth that became alive. Shortly afterwards, the Sartan mysteriously disappeared. Centuries later, the first Patryns escaped the Labyrinth, and have just learned how to access the other worlds. The books follow the fiercely independent Haplo, a Patryn agent sent to scout the four worlds in preparation for conquest by his master.
