Do: Pilgrims of the Flying Temple
A cooperative GMless storytelling game where the player characters are teenaged emissaries and troubleshooters (pilgrims) for a vast temple in a realm of endless air dotted by small floating worlds. Each session is spurred by a letter to the pilgrims¸ which is written in-character but contains a number of ""goal words"" (usually around 20). The players take turns as storyteller. The current storyteller draws from a bag of black and white stones¸ and the combination drawn dictates limits on what the storyteller can narrate. The storyteller writes down one sentence¸ possibly helping the letter's author and crossing off one of the goal words - unless the pilgrim is ""in trouble"". - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
