I am currently developing my own season 8 on the French wiki. I have written 8 episodes and I am currently writing the ninth one. I have created many pages referencing all the new characters, creatures, items, events, spells, places and worlds and made promotional posters. You can find everything right here: https://onceuponatime.fandom.com/fr/wiki/Utilisateur:Author2612/Saison_8
But to complete all this, I decided to build a map of the United Realms to better locate the places of my story. I took all the geographical information I could gather from the scene that introduces the United Realms in the 7x22. I looked carefully at each place and I tried to reproduce all that as well as possible on this map. For the rest, I imagined what could be around by listing the most important places of the Enchanted Forest, Agrabah, Arendelle or Wonderland.
I would love to hear your opinion about the map ! What do you think ? Any suggestions ?
