The resident pack of Arcuileru seeks shelter in a network of caves referred to as Anciaun. The cave is a single hollow, long and slightly narrowed, with some smaller dens in remote corners of it. The pack generally spend their nights in the main part of the cave; some regions are a bit more humid than the outside world, offering relief to the biting desert aridity. The entrance is lined by rows of stalactites and stalagmites, giving some the idea that they resembled fangs. Thus the caves have been nicknamed the Cobra Caves, their namesake these stone “jaws.”
