here are some thoughts on pokemon.
Just off the coast of the Kanto region lies an archipelago known as the Sevii Islands. Accessible only from Vermillion Harbor via ferry line Seagallop Ferries, the Sevii Islands are a series of quaint, quiet, and sparsely populated islands. Climates vary, from cave systems (including Four Island's Ice Cave) to a dormant volcano (Mt. Ember on One Island) to canyons, plains, and forests.
The Sevii Islands are something of a hidden gem for those in-the-know. Famous locales include Resort Gorgeous off Five Island as well as the hot springs and Treasure Beach on One Island. Ace trainers will want to make time for Sevault Canyon (also called Canyon of the Seven Treasures in its original language) on Seven Island. This dry, dusty canyon was the favored training ground of fighting-type masters Bruno (of the Indigo League's Elite Four) and Brawley (of Dewford Town Gym). Those interested in prehistory or archaeology should put aside time to visit the seven Tanoby Chambers, again on Seven Island, or Ruin Valley on Six Island, a known site of sun stones. But remember, leave no trace.
