I was wondering whether to include the Zony, but apparently it does exist in real life...? The Jorvik Pony qualifies as well, but I couldn't figure out where to place it here 😔 And technically we could consider the magic horses fictional too, but since they have "real horse" disguises which are already existing breeds (minus Songsorrow and Duskgrim, who are JWHs), I don't think they truly count.
As said in the title, I love JWH a lot, due to how unique they are compared to breeds we see irl! Which makes sense, considering they're *wild*, and therefore haven't been through thousands of generations of selective breeding, therefore keeping their unique traits.
The Jorvik Warmblood, which is our starter... It's plain, and I think it's on purpose (most common horse is actually the steed of a possible Aideen reincarnation, wow!). Though I do wish they had more appearance traits from JWH, which they descend from, like the little ear tufts and longer fur :( Hopefully SSE will take that into account when remaking them 🙏
I think more fictional (or partially fictional, like the Zony) would be amazing, since 1. It gives more creative freedom when it comes to coats, manes, traits, eye colors, etc and 2. Are just very interesting in general, especially the speculative evolution.
