I know there is a human x Tempest Shadow fic.

Personally I would love to see majestic as fuck seapony/hippogriff (Novo) and/or adorable royal daughter seapony/hippogriff (Skystar) interacting with some lucky human.

Probably not to long I'd guess. There may even be an idea in the works already. I have seen a sired O.C. marries to a human O.C. in another group so there should be at least one at some point.

There's one with Tempest:
