The Seers of Serenity, high in the southern mountains that separate Karigor from Jadame, are troubled. A prophet of their Guild has gone renegade, and is spreading the word that an apocalypse, caused by devilish horrors, is nearing and that Ceth himself, the Creator, will come to Karigor in a final effort to battle this evil and prevent the collapse. The prophet, who calls himself Thelmes, calls for the followers of Sun and Moon to unite and prepare a great sacrifice. As he follows the river Ebony downstream, more people believe his words every day.
What bothers the Seers even more, is that with all their foretelling powers combined, they cannot see if this prophecy has merit or not. Therefore, they cannot interfere. But there may be a way to discover the truth. Scattered over the land, are chapters of the Book of Ceth. Long ago, the book was cut up and the chapters hidden to the eyes of the common people because their contents were thought to be too dangerous for anyone in this age to know in its entirety. Now, so many centuries later, nobody even knows the location of the chapters. If the Book could be found and made whole again, the truth would surely be revealed.
So they called a conference with the leaders of the Clerics and the Necromancers - and found out, much to their dismay, that neither side was interested. Obviously, both churches did not believe the prophecy, but each saw in the coming Sacrifice their chance to rule the world.

Now the Seers of Serenity are going to play a desperate gambit. Against all odds, a party of adventurers will be sent forth to gather the lost chapters of the Book of Ceth. They will have to go in stealth, yet they need to gain the favour of all the lords of Karigor in order to be able to search the sacred, guarded and perhaps even haunted places that might hold the chapters.
Because of the necessary low profile, none of the great and famous can be asked to join in this venture. Instead, the Seers put all their hopes in the young and inexperienced. All they can do to prepare them is to set a short test of promise and loyalty, and any four that will pass this test first will simply have to do.

Still, the Seers are not without resources, and the party will find friends that can help them along the way. Often, these will be followers of the Stars, the third path that - in Karigor and about everywhere else - has been suppressed by the Sun and the Moon alike for as long as one can remember.
The chance that the party will succeed in time before the Sacrifice takes place seems slim. Eventually the prophet Thelmes will reach the city of Terrax in the north, where the river Ebony flows into the ocean. It may be vital that the party is present at every major speech that Thelmes is going to make, because they may learn some important clues from his words .....
