Battlespace

This fancy word refers to the area where the islands duke it out. There are no natural obstacles in this space, but there are threats: The battle area is marked off with a white ring that encompasses the area. Flying outside the ring will cause you to be pushed back into the area. Any loot bubbles that spawn outside the area (mostly caused by destroyed islands that fall down) will be pushed to the edge. Given how unwieldy giant chunks of earth can be, accounting for both your island's mass and the recoil from weapons is not merely recommended - it is mandatory.
