Mata Nui was once an island paradise. The island featured tall icy mountains, deep ocean bays, wide desert expanses, caves deep underground, lush green jungles, even a volcano. The island is surrounded by seemingly infinite seas stretching out to the horizon, which are aptly known as the Endless Ocean.
