Haplo the Patryn has been ordered by the Lord of the Nexus to explore the elemental realms—Arianus, Realm of Sky; Pryan, Realm of Fire; Abarrach, Realm of Stone; Chelestra, Realm of Sea—and to instigate chaos where he can. Though Haplo discovered his archnemesis Alfred the Sartan early on, the two were drawn to one another and came to travel together more often as time passed. Side by side, they found small bits of forgotten information that help them understand the long-ago Sundering of their universe into four realms.
