Unicorn- horses with long, straight horns growing from their foreheads and tails like lions. They are generally sturdy, muscular animals with plenty of stamina and tough hooves that are sometimes cloven.
Pegasus- horses with feathered wings. They are smaller than unicorns. Their heads are slightly dished/concave, like an Arabian horse's. Pegusi are agile and have keen eyesight.
Hippocampus- horses that have the back end of a fish or dolphin rather than hind legs or tails. They have long, narrow faces and gills in their necks near their head.
Hippogriff- a creature with the front half of an eagle, with an eagle's legs and talons, and the hind half of a horse. In Paimere they are known for being a warlike, bloodthirsty species.
In addition to these there are the unisus, a pegasus and unicorn cross, who have their own kingdom. Their kind is diverse; some have wings or horns, others don't. They tend to be rather aloof, since in the past unicorns and pegusi have been viewed as "pure" and the unisus as not-as-good.

In the center of the continent is Paimere Capital, a large, grand building where the rulers will hold meetings in times of peace.
There are smaller kingdoms within each realm, where 'secondary royalty' lives - high ranking horses, like nobles and descendants of ruler's siblings, and small royal families.
(NOTE: This story is about anthropomorphized horse-related mythical creatures, and so I've included a glossary of sorts at the end to help those of you who aren't very familiar with horsey terms - words such as stallion, mare, mane, etc. Made-up words for the story are listed there also. Plus, if you aren't into that kind of stuff now you know and you can wander elsewhere on the internet.)
