Berserker Island appears to be a very rocky, bare island. It is very 'vertical', having a tall central mountain with very little spread of hills of fields around it. The rocky central island is surrounded by significant sea stacks. The island has trees and grass, and a large amount of white-flowering bushes closer to the village proper. The interior of the island has a "maze of caves", in which ice structures can be found, which were created by a Bewilderbeast. The caverns are so extensive, the mountain is practically hollowed out.
