Arsinoitherium are large two-horned ancient rhinoceros-like creatures that have existed since the dawn era. Long distant cousins of Mammoths and Horkers. They stay warm through their thick layer of fat and having a relatively low surface area compared to its volume to keep itself warm. They also have other body mechanisms to keep itself warm in nearly the same way frostbite spiders do to keep themselves from succumbing to the cold.
Two populations of Arsinoitherium can be found in Skyrim, one group in Hjaalmarch and the other in the geyser fields of Eastmarch. Theres also another population that resides in Elsweyr, but how these populations have cross providence's still puzzle scholars to this day. Arsinoitherium live solitary lives and are protective of their territory, a charge from these three ton beasts can be fatal if one stands in their way.
Last but not least, they also use custom sounds and loot. Enjoy!
P.S. Yes I know they don't fit in the cold environment as they lived in warmer climates in real life, that doesnt mean I won't try to create lore explanations for them though. I need these creatures made for a Hircine mod idea that's inspired by Ark Survival Evolved. However I don't want to make the creatures be exclusive to the mod as that would suck for those having to wait for that to be finished. In case it never gets done, I'll still have these individual creature mods for you guys to enjoy.
Big thanks to RoboBirdie for the meshes and textures, and also big thanks to Rexy Montero for the sounds.
