Gaia walkthrough

9 parts, one per checkpoint Gaia’s own documentation defines: the areas each one opens, the wild Pokémon and trainers in them, and the fight at the end of it. Everything here is read off the game’s own files, so anything it doesn’t state isn’t claimed.

It also doesn't say when Rimewood Forest opens up, so it is in no part above; it has its own route page.
