The island and town of Odila had once been a popular port for pirates, as it's sheer remotness made the Marines uninterested in keeping an eye it. For several years, the town was allowed to flourish, and became the base for several small-time pirate crews.
Eventually, as pirate activity in the area increased, the Marines started to take note of the island, and sent several ships to find it. Following a careless pirate vessle, the Marines located the island and razed the city to the ground, killing most of the quarter million inhabitants. Only a few people escaped, including Ezekiel Mori .
In recent years, the Pure World Pirates have built a fortress there, once again making the island into a pirate base.
The island is shaped more or less like a tear drop, with the northern most part of the island being a wide semi circle that gradually tapers to a point in the south.
The island is rather forboading, with much of the northern coast line consisting of sheer cliffs; the only beach is at the southern tip of the island, and the water is dangerously shallow here, making it perfect for smaller vessles while discouraging large ships.
At one point in time, the island was heavily forested, but most of the trees were cleared away to make room for the expanding city of Odila, which came to cover the entirety of the island. After the city was destroyed, the ruins were left abandoned for several years, and the forest has begun to reclaim the island.
