You do not need to be active in, or familiar with, the Torn World setting to participate - you can ask for more of the kind of story or poem you particularly like (happy? sad? romantic? featuring a particular class or type of person?), or leave a generic prompt (blue, clouds, oblivious), or ask a burning Torn World question that has been bugging you (how DO they milk a snow-unicorn? or what is the primary export of the Affamarg area?)!
