Geathian horse

We don't know the name of this thing.

But we do know where it came from. So we're using that to title the page logically. If you know a better, more precise name, tell us.

A Geathian horse was a horse found in and around the city-state of Geath on a certain planet. Rory Williams was surprised by their very existence, because he didn't consider that there were horses on worlds other than Earth. (PROSE: The King's Dragon)

Behind the scenes

Although the name is a demonym, the demonym is actually used in the text of Dragon. People from Geath are Geathians, so horses from there are plausibly Geathian as well.
