Can you provide some more elaboration on what you mean by "form the world around us"?

Yes I can. The way I imagine it we'll be thrown into the world at a random place (In the forrent, middle of a city, outside a dark cave...). We have no map, and no part of the world (or the things in it) except our characters are known to us. We'll have to explore to find out. The player who writes the next post is free to make up what comes next, and the other two can then react to whatever that is and then either go along with it or make something new. 

Is that clear enough or did I miss anything?
English is my second language by the way, so don't hesitate to ask if I'm not making sense :)
