An Imminent Spark is a story game for 3-4 people without an MC or GM.  A game takes somewhere between one to two hours.  It's about 1000 words, printed as a 5.5"x5.5" 32-page saddle-stitched zine.  Aside from the rules, to play you need: a flat surface, about a dozen tokens, some candles, and darkness.  

Each Custodian picks a Mantle, an aspect of beauty that they stewarded.  You take turns making up stories about art, nature, tradition and social change.  

In the end, it all falls apart.  But you'll have a chance to seed the next world with something beautiful to get it started.  

Note: The Deluxe version comes with the Dark Cards and Mantles as physical play aids.
