Occam's Razor is clear here. Crossing dimensions is neigh impossible, he must simply be insane. Though, try as he might to acclimate he can't help but question the sanity of these ponies and their odd social practices.
I'm just a guy that likes ponies. I'm a fan of herd world building stories though not so much when they're just harem scenarios. I've also acted as an editor for a couple stories. How goes it?
