Crescent Island is a crescent-shaped island on the very southeast edge of the south blue. It is of a large size, and is mainly uninhabited. There are two villages on the island: one on the small, star-shaped island only a mere 5 kilometers off of the coast of the main island, and another village at the base of the volcano. These villages are inhabited by the native people who settled there centuries ago.

Crescent Island is a highly vegitated island, resembling that of a jungle. On the northern part of the island there lies a large volcano. The natives say that it will only blow once they have disgraced their god in some way.

Crescent's wildlife includes that of the jungle: monkeys, gorillas, tigers, and highly venomous snakes.
