We need to catalog our PMs very precisely, with all the different story lines with so many characters, it sounds potentially messy with parties splitting up and partially reforming before breaking up again. Also, the chronology of all the events is going to be a pain to keep track on with players meeting up at different points in the game and stuff, especially if a character keeps jumping around parties or if someone does something to have a lasting impact on the labyrinth. Maybe have time markers every now and again so that the characters can have events happening to them relative to in game time instead of character- specific events?
