Pokémon Abandoned Ruby

STORY:

You’re so excited to go to Hoenn and catch new Pokémon but you find out the HOENN region is abandoned, or is it… :0
NOTE: After you “beat the game” and talk to your ghostly Mom and Dad. Go to Slateport and go to the harbor and DO NOT go to Lilycove, this will be for later.
Then beat the YOUNGSTER gang, then leave the safari zone and go to Lilycove and beat Steven. Play the game to find out the rest.
