Domesticated Terrors
These massive creatures were once inhabitants of the seafloor caverns before The Cataclysm. Since then, they have been nearly exterminated to secure water supply before they were domesticated and brought back in numbers. Their adaptation to living underground has also made them entirely reliant on their sense of hearing to navigate the world, obvious by their alien head entirely lacking in normal beastly features.
Though they are unpleasant to look at, the strength of their massive frame makes them well suited as pack animals. They are also able to sustain themselves directly off of minerals from the ground which they can dig up themselves using their hard, spiked forelimbs. Those appendages also make them excellent at digging mines or expanding tunnels for water, something that can be useful if one is stranded without water on a long journey.
