Endgame: Sky Key

Several decades before the Players of Endgame met at the Calling, an earlier generation of Players is learning the rules. Each has been chosen as the one to save their ancient bloodline—and win Endgame. But not everyone wants to see Endgame take place. A group of conspiracy theorists called the Zero line will do whatever it takes to stop Endgame from happening. Their plan: kill the Players before Endgame even begins. Their mission: save the world. Endgame is real. Endgame is coming. But the Zero Line will win.
