Ignore the journal, and kind of a shot in the dark, but a Guardians of the Galaxy darker AU PSL? Idea under the cut due to spoilers. I was kind of wanting a psl based around Ego corrupting Peter after showing him the answers, before he was told about the intentional death of his mother. Also would love to build on the idea even more as it's a basic one for now.
I'll happily write against canon, or Oc characters.
