I searched online and couldn't find anything anywhere. Can someone please help? I want to know what this strange occurrence was; it's really bugging me.
I've heard that there are wild horses in Oblivion, but never seen any myself.
It's apprently a very rare spawn in a section of Cyrodiil, between Fort Alessia and Fort Homestead, according to UESP. I did see them yesterday, and right now I am not running any mods that spread their spawnpoints, so it must be a rare occurrence, or I never ended up right exactly where they do spawn before, both very possible.
And reading the UESP page, apparently if you get a wayshrine blessing to also cover your horse by having them atop the shrine, it speeds them up permanently. Man this game just has lots of little things in it, I dunno if I will ever be able to say I know everything about it.
Yes, there are wild horses in the vanilla game. I never saw wild paint horses in my games, but I did see the bays. UESP:
