1.25  The RETCON Rule

             Retcon is short for 'RETroactive CONtinuity.'  Sometimes a player makes a
 mistake, for instance posing that they polish their sword when the sword was dropped
 elsewhere earlier.  The polite thing to do is for the player to make a quick OOC
 announcement that the previous action didn't occur, and for other players to go on.
 (Acknowledge the retcon with PRIVATE pages please.)

             You can only Retcon something that just happened.  You can only Retcon your
 OWN actions.  The purpose of a Retcon is not to explore a tree of possibilities
 relying on different decisions or let a player make up for an action that results in
 something they don't like.  The purpose of a Retcon is to repair damaged continuity as
 quickly and smoothly as possible.  Retcons can't be used to "take back" an action with
 a dice roll involved.  Whether you succeed, fail or fumble, that action has already
 taken place in the game's continuity.
