The crater and the Arctic Mega Biome are the two major ecosystem centers known on Planet 4546B. The area is the crater of a huge, long-dormant undersea volcano approximately three kilometers in height and two kilometers in diameter. After the volcano became dormant the crater was filled in by sediments and the once volatile volcano became the center of a diverse and thriving ecosystem. The area around the volcano is known as the dead zone or crater edge. It is a barren expanse of empty water inhabited only by plankton and their planktivorous Leviathan class predators.
