The Gorusk, just like the Homo Inhumanum, is a new species ands seems to be related to elephants and rhinoceroses. However, unlike rhinos and elephants, gorusks do not seem to be herbivores. Instead their favourite diet is mineral rocks. As such, the ruins of the old cities are a perfect feeding ground for Gorusks which happily chew away at the abundant cement and asphalt. As a consequence of the Gorusks eating at the foundations of buildings, many buildings have collapsed on top of the greedy animals, killing them in the process. This has led Brutes into herding the animals into safety while eating so as to prevent them from accidentally toppling buildings on top of their own abodes.
