Knot Island
Knot Island is the first island in the Sevii Islands archipelago. It is the most northwest of all the islands. Knot Island is an isolated little place, and most of the younger people living on the island are eager to leave for big cities.

Boon Island
Boon Island is the second island in the Sevii Islands archipelago. It is east of Knot Island, and west of Kin Island. The water to the east of the island is flowing too roughly, therefore, it cannot be Surfed upon.

Kin Island
Kin Island is the third island in the Sevii Islands archipelago. It is east of Boon Island. Kin Island, like most of the other Sevii Islands, has a town on it, Three Island. It is the most populous town of the seven, but unlike towns in mainland Kanto, it is a very sleepy town.

Floe Island
Floe Island is the fourth island in the Sevii Islands archipelago. It is south of Knot Island, and west of Chrono Island. The town of Four Island is the hometown of Lorelei of the Elite Four. It is here that she was first taught about Pokémon when she was just a young girl.

Chrono Island
Chrono Island is the fifth island in the Sevii Islands archipelago. It is south of Kin Island, and east of Floe Island. On Chrono Island, much like on the previous islands, is a town, by the name of Five Island. It would seem that the island is expanding in population lately.

Fortune Island
Fortune Island is the sixth island in the Sevii Islands archipelago. It is south of Chrono Island and east of Quest Island. On Fortune Island there is a small town, Six Island, where many say that the view of the stars is amazing, away from the bright city lights of the mainland.

Quest Island
Quest Island is the seventh island in the Sevii Islands archipelago. It is south of Floe Island and west of Fortune Island. Quest Island, like the other Sevii Islands, has a town on it, named Seven Island. Quest Island does not have as many inhabitants. It has been left virtually untouched in its natural state; it is difficult to hike across.

Navel Rock
Navel Rock is an island between Floe and Chrono Islands in the Sevii Islands. It can only be accessed by sailing there by taking a Seagallop Ferry, or (if in Hoenn) by boarding the S.S. Tidal. It is said to be home to Legendary Pokémon.

Birth Island
Birth Island is at a location near Fortune and Quest Islands, in the Sevii Islands. It can only be accessed by traveling via the Seagallop Ferries' dock, or (if coming from Hoenn) the S.S. Tidal. It is said to be home to a Legendary Pokémon.

Territorial Waters
The area that encapsulates the Sevii Archipelago, butting up against the Seafoam region to the north and the Orange Archipelago to the south. The Sevii waters are sometimes calm, but sometimes rife with hidden redoubts and small shards of islands that call forth adventurers to find their rare Pokémon.
