Seven Keys to Doomsday has its roots in a stage play from before Tom Baker was cast as the Fourth Doctor. However, we cannot take the original stage play as a valid source per T:VS, so the only potentially valid version of Seven Keys is the Big Finish version. We have determined that the Big Finish version fails rule 4 of our four little rules because it was not intended to take place in the DWU as it existed in 2008.
