The Hyperion Prophecy
There are three seals, each with three locks.
One lies beneath a dead city, its guardian now departed.
One is deep inside a bottomless cleft in the north of the world, guarded with a test of dark faith.
One is on the mountainside at the end of a trek through heat and mist.
The spiral-bound seek these out, but another threat looms. Atop mighty Jericho, a scholar watches. He will see the terrible light that descends from above.
