Going to spill the beans before I go into any territorry.
I want to write an SCP (tale maybe) linking the SCP universe with the RPC universe.
Obviously I am asking here because I know these communities don't like each other, so I would rather be safe than downvoted and deleted.
A Rough sketch about the idea: A low-level researcher somehow ends up in a situation where SCP captures it. Maybe from an other universe where there is RPC instead of SCP. Maybe the same world, both GOI coexisting without knowing about each other. After being captured they begin talking. The "subject" would be low level so he wouldn't know much. After some time the researcher would return to it's place (teleportation, MSF recapturing etc)
This incident would be present in both universes/GOI , from different perspectives.
Just thought of this, hopefully you like it
