Crescent Island

Crescent Island, also known as The Moon-Shaped Island, is an island located within Paradise. Having earned its name thanks to its crescent moon shape. It's the island where the Runa Runa no Mi originally came from.

Geography
Being a Summer Island, Crescent Island is always blooming with green color. It's temperature by by day is a steady 32°C (89°F), and by night it's 24°C (75°F). The island is split into two halves. The main half is on the inside of the island, and the other half is the outside of the island. It's seperated with large, green mountain ranges. It's a small island with too much space being taken up by mountain ranges. Thus the population of the island is pretty low.

The island has a unique phenomenon where the water inside of the crescent form is in fact freshwater. Within it lives very passive wildlife, and thus the sea of the Crescent Island is considered to be very safe.

Past
The history of the Crescent Island is an insignificant one. The people living on it cooperate together and thus don't need to rely on the help of outsiders. There was never any conflict between it or other islands. It's also only rarely ever been raided by pirates.

However, there was a very conflicting pirate invasion before. One of a mysterious, independent pirate. While raiding, he came across a particular fruit. The Runa Runa no Mi, which gave him powerful Logia-Type abilities of moonlight. Considering how a fruit like that was found on a moon-related island could not have been a coincidence.

Ever since that encounter, the island has become very cautious of outsiders. People fear that outsiders would come to the island in hopes of finding the fruit again. Even though it hasn't been found again, even after the pirate's death, the citizens are on high alert. Not wanting to have their peaceful island be plagued with conspiracies or ill-natured rumors.
