One Island (town)

One Island (Japanese: １のしま Island 1) is a small town located on One Island in the Sevii Islands. The only major defining point of the town is the Pokémon Network Center, run by Celio, a friend of Bill.

South of the town's Seagallop Ferry dock is a short watery path to Treasure Beach, while east of it is the challenging Kindle Road. As it is such a small town, many more things can be done on these two routes than in the town itself, though players will find themselves brought back here repeatedly in their quest to use the and  to complete the Network Machine.
