I know that horse commands give you a feature to control your horse, but I was wondering if there was a mod just for shadomere. I remember the first time I saw it arrive in the pool. That was quite awesome. It reminded me of Darksiders. I think the summon / banish of Ruin was pretty well thought out.
I also think a mythical horse like Shadowmere could benefit from a mod like that. Nothing fancy, just a conjuration spell that would summon/banish the steed using the aforementionned effect. It would also give direct control over it and it would stop its killing spree.
