Aurochs

In the Red Rising Saga, Aurochs emerge in Morning Star as imposing, shaggy-coated steerlike herd animals that Obsidians ride across frozen terrains, their massive frames carving deep imprints into the snow. These creatures underscore the raw, primal power of the outer worlds and the symbiotic bond between Obsidians and their environment. Their presence enriches the saga's world-building by illustrating how different castes harness unique fauna amid escalating rebellions and interstellar conflicts, adding layers of cultural and tactical depth without further evolution in later volumes.
