The Draconic Prophecy

There are patterns hidden in the world. Secrets lie in the conjunctions of the planes and moons, in strange symbols formed by the flowing lava of a volcanic eruption or the fissures caused by an earthquake. Carved in the walls of ancient citadels and on primeval megaliths, knot patterns appear to have meaning that only the contemplative mind can hope to comprehend. To those who can read them, these myriad events and signs form a map of possible futures, a map that can be used to shape the course of history.
Scholars call this map the Draconic Prophecy, attributing it to the Progenitor Dragons: Eberron, Siberys, and Khyber. The Prophecy is vast and complex, its signs scattered across the world. Few humans or even elves have the time or resources to unravel its secrets. The foremost students of the Prophecy are ancient dragons, immortal fiends, and others who have devoted thousands of years to this work.
What makes the Prophecy especially complex is that it doesn't define a singular path for the future. Rather, the Prophecy is a map that shows many possible futures, along with the steps that must occur to make that future a reality. A fragment of the Prophecy might say, "If the Bear King is slain by a sorrowful assassin in the Shadow of the Mourning, the Crown will fall from his nation." The "Bear King" could refer to King Boranel of Breland, since the bear is Breland's heraldic beast. The "Shadow of the Mourning" could mean that Boranel must be slain in the Mournland, or it could mean that the assassination must occur on the anniversary of the Mourning. This passage doesn't say that Boranel will be assassinated or that the Brelish monarchy will fall; it suggests that if Boranel is assassinated under these conditions, then the monarchy will surely fall. But it could also be fulfilled in different ways, if the terms of the Prophecy are interpreted differently. Other fragments of the Prophecy might cover what happens if Boranel is assassinated under other circumstances, or what happens if he dies of natural causes.
As an adventurer, you could be hired by a scholar trying to piece together a fragment of the Prophecy and clash with a secret society along the way. Or you could discover that your family plays a pivotal role in a fragment of the Prophecy. Will you embrace this or fight your potential destiny? Will you dedicate your life to interpreting the Prophecy or ignore it as just a bunch of mystical nonsense? And might the Prophecy hold the answer to the Mourning itself?
