The dice are rolled and the result is retro-actively interpreted. The player can fabricate details, incidents, torches being forgotten… whatever… as long as it all explains the outcome. This ‘rear-loading’ of the task resolution frees the player from having to establish in some detail the surroundings and features around the character, before being able to make a decision. There is still some work to do however — the player cannot make a Plan without some information. But he will not have to create guard rotas, building layouts, descriptions of labs or corridors, or how the alarm systems will have to be disabled. It is this shift to fortune in the middle that allows us to roleplay effectively without a referee.
