The Mythryn Gambit
For every one of the Renewals, there is an Endgame. Although it is not operationally defined, an Endgame becomes apparent when physical signs point to the end of the world. Usually, it is characterized by curious properties of elements. Water may move of its own volition without a force acting on it. Fire may spontaneously flare up in trees, then sputter out. One account even explains that a lightning bolt struck to the ground, but turned away at the last second. It traveled parallel to the ground, destroyed several homes, and then surged back into the clouds.
Sometimes, early in an Endgame, the sky becomes a dull red at all times during the day. Even if they are not rain-clouds, all of the clouds in the sky resemble smoke. Finally, in the last hours of the day, the primordials break their chains and enter the world. The barrier between the gods and Mythryn, too, is broken, and each of the deities travels to the world. Covering what ground they can, the deities appear before each worthy soul they can bring and meld their spirit into their form.
Thousands, even millions die on these days. Even deities have been known to perish. But in the end, when no mortals remain, either destroyed or claimed, the deities do battle with the primordials. With the Mystic at their aid, the deities triumph, but the world is destroyed. With that, there is a day of rest… afterward, the game renews, and the deities see how they fare with the new Mythryn.
