|This article is about the Arctic. You may be looking for the Sparse Arctic or the Arctic Spires.|
The Arctic regions are large biomes characterized by rugged, rocky terrain on the seafloor and icebergs on the surface.
There are two regions, one located to the east and one to the west.
The East Arctic seafloor is relativity similar to its western counterpart, apart from the large, resource-rich dormant caldera that can be found near the border with the Lilypad Islands. This caldera appears to have since scarred the nearby landscape with small trenches and fissures in which many resources, such as Lithium, Ruby and Diamond, can be found as well as few Large Resource Deposits. A Chelicerate patrols the caldera, however.
In the center of the caldera is a Ground Sampler.
There is a cave system found inside the largest iceberg in the biome, located East of the caldera. If the player swims up the cave they'll find a sealed ice hole which must be cut with a Laser Cutter. An Ice Bubble can be used nearby to replenish oxygen. Once cut, the player will be able to swim up and out of the water into a cave containing Ore Veins filled with Magnetite and Diamond.
The West Arctic's northern reaches are dominated by a sprawling collection of lively icebergs. Both underwater and surface vegetation is much more common in the West Arctic than its eastern counterpart. The southern portion of the biome is absent of icebergs but supports multiple blooms of Eye Jellies under the waves. Large, rocky formations cover the seafloor of the West Arctic, including large boulders and large hill ranges. The seafloor also hosts small pockets of flora littered towards the northern portion of the biome, underneath the icebergs.
- The Arctic used to host a small group of Sea Emperor Leviathans before they were cut completely due to story change.
