Paradise Island

Paradise island is a small island on the bottom left of the map. The island is only half accessible due to the world border, and attempting to move past this border will result in death.
It doesn't feature any points of interest such as resource nodes, cracked boulders, oil, drop pods, stingers, hogs, or other hostile enemies.
The island was planned for removal but community backlash resulted in Coffee Stain Studios deciding to keep it. In an AMA, Snutt Treptow explained that the kill border had been moved in the 1.0 update to allow players to access more of the island.
