Outside of the city borders, pockets of life can be hard to find among the corrupted wasteland. They are still there, however, in the protective borders of the Proto-ARKs. To the southeast, the Desert Proto-ARK exists. To the north, the Snow Dome, a second Proto-ARK. Another exists to the northwest, called the Sunken Forest, which was supposed to be another ARK but failed when it collapsed into the ground, presumably due to there being a large sinkhole underneath it.
