Oh, imagine a little wooden chest with drawers that never quite close, each drawer a different kingdom or a character’s backstory, and inside tiny cards that hold everything from the color of the moon in the night of the dragon’s eclipse to the exact cadence of a hero’s name when it rolls off their tongue. I’d paint each card with a tiny sketch, a line of dialogue, a rule about how a magic spell feels in the air, and stick a ribbon that ties it to other cards—so you could pull a thread from one world to the next, just like pulling a string of fireflies. The system would let me slide a new realm in and watch the whole tapestry shimmer, while the cards keep the tiny details humming in my head. It’s like a living puzzle that’s always ready to shift when a new idea takes flight.
