The fifth of the seven Sevii Islands. Chrono Island is possibly the biggest island in the chain and consists of a smalll town next to a meadow, on which an abandoned Team Rocket warehouse stands. Past the meadow is a memorial to a Steelix that has passed away. To the north of the town is a water route called the Water Labyrinth. Farther north is Resort Gorgeous, home to a wealthy woman named Selphy. Past Resort Gorgeous is Lost Cave, a cave covered in thick fog swarming with ghost Pokemon.

Chrono Island is accessible by ferry from Vermillion City, Olivine City, or any of the other Sevii Islands.
