  • As with Temporal Platinum; there are a LOT of worldbuilding hcs going into this
  • there might or might not be a warning added as I add more chapters to this
  • there are a LOT of worldbuilding headcanons I got for this
  • just trust me
  • some of the headcanons here have been inspired by Doctor Who
  • I forget the word for it but I hc the legendaries being able to take human forms
  • Fictional Religion & Theology
  • Grief/Mourning
  • Aura (Pokemon)
  • i can't believe that's a tag
  • Rei haunts the narrative so much that his tag is justified tbh
  • some of the legendaries in this fic are shiny btw
  • Worldbuilding
  • Heads up: Lucas’ grandparents are Terrible People
  • not Ghetsis Harmonia level terrible but still pretty bad
  • Nonbinary Character
  • Palkia's nonbinary and questions are asked about it
  • because Vesper/Palkia is nonbinary
  • I might have implied it in Temporal Platinum but here I'm gonna outright SAY it
  • Said legend is also in their human form for this whole thing just a heads up

  Summary

  Because I got so many headcanons for Sinnoh that I may as well consider these fics a whole cinematic universe. Hope you enjoy.
