Sorry! Yes, it's rot13, translatable quickly with, say, https://rot13.com/. (Serves me right for coming from a world where that's immediately recognizable and therefore forgetting to explain it.)
okay i think i found the bug,
the "[6]" is meant to be an "E", let me fix it
There's already an E as part of its set; it should be pointing to that E, as far as I can tell.
doesn't matter, i already remade the entire puzzle to be better
