I'll put together a "Powered by 7:7" logo sometime soon, I should have done it long ago anyways :) I think that the Mork Borg license probably needs to be included if the 7:7 one is just because it's kinda subsidiary to it? But I honestly don't know the answers.
Fleeing is indeed having all the Monsters deal their damage and get discarded. This happens when you play a fresh Location card from your hand while there are enemy Monsters in play.
