And as the story grows, it feeds back into the game. When one of those Planeswalkers, Gideon Jura, died in that new novel, Wizards of the Coast released a set of eight new cards commemorating his life and powers. The company called it a “Signature Spellbook”—classic Gideon-related cards with new art. You see how this works, right? The game can generate and absorb story. “A game mechanism is a kind of cosmology, whether you want to recognize it,” Kelman says. “We want to create a cosmology that honors the game mechanisms without literalizing them.”
