From the rear cover Menagerie of the Void is a storytelling game for one player. You play as the keeper of an ancient menagerie, created by a long-gone society and still operating. You create the story as you play, writing down some details, deciding how to care for the exhibits, and drawing cards to see what happens next. It takes an hour or two to play, using this booklet, a bunch of index cards, and a deck of regular playing cards.
