Every time I try to ride a horse anywhere off the main highways I always get ambushed by a bear. It's like a really unfunny joke. Yep, the creatures of Cyrodiil really, really hate horses. I once had danger music follow me all the way up the Cheydinhal road. Worried I'd get the permanent danger music if I entered the city, I parked my horse in the stable and walked down the road a bit. There, I drew my sword and waited. Eventually, a minotaur came running up the road. I stood there defiantly as it charged straight toward me. I swung my sword as it blew past me and managed to hit it in the side. The minotaur wasn't even phased, it just kept running up the hill. By the time I hoofed back up the hill, the minotaur had opened the stable gate, killed my horse, and was now fighting the stable hand and the guard. Bandits seem to have a grudge against horses too. I've had more than a few completely ignore my slashing blade because they were dead set on killing my horse. you might have gone too close too the unicorn, its guarded by two minotaurs, i was just walking through the forest one day and one attacked me and then the unicorn attacked me.
