Five Island
Chrono Island is the fifth island in the Sevii Islands archepelego. It is south of Kin Island, and east of Floe Island.
Chrono Island is also known as "Five Island". The island's motto is "Chrono Island: Where Time Goes".
It would seem that the island is expanding in population lately, although this has caused the fish population to drop.
East of the port is Five Island Meadow. It is a field owned by a local family thoughout generations. However, members of Team Rocket took it over and built a Rocket Warehouse there. They bullied the locals for a while, not knowing that Giovanni had been defeated already. Once news of his defection from Team Rocket was announced, the Rocket Grunts abandoned the warehouse and gave up the Sapphire they had stolen.
West of the port is the Water Labyrinth. The Water Labyrinth is a ocean past through a series of rocks. At the very end of the path is an old man who will give a Togepi egg to the trainer who reaches him.
North of the local town is Resort Gorgeous, owned by Lady Selphy, a rich socialite who likes to go exploring in the Lost Cave. Selphy invites artists and other high-class people to private parties on the island. If the main character of Pokémon FireRed or Pokémon LeafGreen defeats her in the cave, she will ask the main character to show her a certain species of Pokémon. Doing so will garner rewards from the wealthy woman.
Off the coast of Resort Gorgeous is the Lost Cave. Thrillseekers enter it full of curiosity. Many never leave. The cave is a confusing maze that makes no sense.
The very south tip of the island is home to the Memorial Pillar, where a young man has built a gravesite for his deceased Onix. The grave itself appears to be the tail of the rock snake Pokémon, emerging from the small islet. The trainer will be grateful to trainers who leave offerings of his Onix's favorite beverage - Lemonade.
To reach this island, a person has to have a Rainbow Pass, instead of the ordinary Tri-Pass.
