Northern Expedition

Overview

The Northern Expedition is a large mountainous island which features many ice and snow-themed fish. It can only be accessed via a portal in the main map, and is one of the only locations that exist outside of the main map's boundaries. It is considered as part of the First Sea. The Northern Expedition consists five sublocations; four out of the five sublocations are currently the only places in the game where the player's Oxygen level decreases gradually. The player also loses Warmth, posing a risk to exploration. Blizzard and Avalanche events occur only at the Northern Expedition, but their respective mutations will be available anywhere.
