Horse is, frankly, impossible. Horses don't become ghosts. They also don't have 7 Forces in life. Unfortunately, nobody seemed to explain this to Horse.
It's guessed that, in life, Horse was, well, a horse. From its appearance and behavior after death, it was apparently a racehorse that was used in the old holiday of Benididea: at least, that's what the expert (a Greek blessed soul) said, and there's no real reason to disbelieve him. Presumably it died in the middle of a race.
Horse has appeared several times over the last few thousand years, and seems to have no other purpose but to manifest, gallop at full speed for as far as its focus will let it, then disappear. During this time, an even more ghostly rider appears; this just seems to be an illusion, because attacking it does nothing to harm Horse. It does anger the ghost, though, who will then proceed to attack in its turn for a minute or two, then disappear.
Despite its skill in combat, the Host could easily destroy Horse. However, angels don't do that sort of thing normally: besides, the ghost is a particularly interesting mystery. Unfortunately, nobody's ever been able to figure out how Horse came into existence, or what's keeping it on Earth. As long as no one actually attacks it, Horse doesn't actually harm anyone, so the Host just keeps an eye on it and occasionally assigns somebody to investigate the mystery.
Campaign Note: Horse is pretty much meant for local color: as written, it won't have any real effect on the campaign. It's just a ghostly horse that will run like Hell through a scene - several times - for the express purpose of reminding the PCs that there's stuff out there that nobody understands. If the PCs decide to investigate, and the GM feels like giving an answer, the actual reason for Horse will need to be decided. Possibilities include:
Or, indeed, anything that tickles the GM's fancy. Whatever the solution, it should involve a good deal of research and, preferably, treasure of some sort (which will justify combat, if desired): treasure is always a nice touch when doing a ghost story.
Sugar cubes are optional.
