Wouldn't the cherubs' session be technically post scratch because it's sort of post apocalyptic? Perhaps a pre scratch counterpart will be introduced later... Which leads to the question; could a one-player session like Caliborn's lead to a Scratch?
The Cherub session is not a post-scratch session. It couldn’t be scratched because you need Echidna’s needles to scratch the Beat Mesa and there is no Echidna in Caliborn’s session.
