Welcome to the world of Mythryn, where the Great Game takes place.
The world is a battleground for several hundred thousand souls created by the deities to war against each other for survival. In Mythryn, the gods play chess with different numbers of ‘pieces’ depending on their performance in the last game. At some point in the middle of the game, whether it’s been centuries or merely days, time is up.
Apocalyptic events occur, wiping the board clean of souls. The deities gather up what powerful followers they can with the power they have and proceed to the next game, recreating the world and forcing the primordials of the apocalypse back into slumber.
The deities do not fully understand the cause of this game, only that they must abide by the rules set down by an unknown force. You see, the gods could not truly wrest power from the primordials when they wished to take the world for their own, as they were weaker. So, the deities cut a deal with someone (or something) they did not truly understand: they appealed to a higher power to weaken the primordials, so the gods could maintain power over the world; however, the force would be the natural beginning and end to all things, save the deities themselves. Waging a losing war, the gods agreed, having already lost dozens of their numbers. With the help of this force, the gods were truly victorious, slaying what primordials they could and forcing the others into exile or bondage. After the war ended, though, the gods could not abide fully in harmony. With such different views, the gods were bound to have conflicts.
The force appeared in a shadowy form, neither a primordial nor a god. He made a proposition: the world would be created equally by all the gods, creating their own realms and nations. Based upon the number and value of the followers remaining at a set date, the deities would grow or decline in power… and the world would start anew. The greatest of the gods would have the most power to shape the world in their image.
Then, he set them against each other.
Over the course of several “renewals,” the deities diverged in power. The ‘Mystic’ as he is called, watched over the game, and when gods ran out of players, he slew them instantly. In kind, whenever a deity perished, all of his mortal followers died as well. The pieces and the players are inexorably linked… but to what purpose? Who is this Mystic? Why does he play this game? And what part do you have to play in this game?
