Yog

'' The Yog is a mysterious creature resembling a big Arachni but with a deformed human-shaped head. All clues point to a bioengineered species. Evidence was found of Cultists dabbling in advanced transgenics. DNA samples revealed a mixture of Arachni and human DNA. DSEC military advisers refer to these as biotanks, pointing out this is a clever way of creating low maintenance, self-repairing weaponry and excavation bio-tools, suggesting we should allocate further resources to research this advanced transgenic creature for our own purposes. The Yog is not only biotank-employed by Cultists, but also effective excavation tools. Exploration drones caught video footage of a group of Yog carving out a tunnel with a speed that puts some of the best DSEC equipment to shame. ''
