Horses

Horses
Animal, natural beast, trained. Mortalus.

Horses are a common friendly animal that is often domesticated and used by Orans for labor and transports. There are some varied types of horses that can be found. Including normal horses, work/plow horses, and wild horses. They will fight back if you attack them but I guess I would not even rank this as a Beginner monster in my ranking system.

War Horses
Animal, natural beast, trained. Mortalus.

It's not uncommon for warriors to armor up horses and even train them to attack people. This is ranked as Standard-Adept monster in my ranking system.

Hell-Horses
Monster, demon, trained. Meldoran.

These are not even really horses but horse-like demons from Meldorin. It is rare but I have seen people use them like normal horses and even armor them. Without armor I rank this as an Adept monster and with armor and training I rank it as an Epic monster. Only for the skilled and really skilled to take one-one-one.

Nightmare
Monster, dream beast. Dormilhiym.

These horse like things live in Dormilhiym aka The Dreamscape. There are said to give any who encounter bad dreams, but seeing as you were likely already having one if you encounter it so it's like having a bad dream inside a bad dream. One can only imagine how horrible such a thing would be. I rank this as a Mythic monster so only demi-god like people should one-on-one it.

Unicorns
Animal, magical. Mortalus, Arcana.

Very rare friendly animal. It is said that only one truly pure of heart can even see one. I guess I'm not pure then as I have yet to see one. I will not bother to rank this monster.

Pegasi
Animal, magical. Mortalus, Arcana.

Winged horses that are somewhat rare that some have managed to tame and even ride. I'll rank these at adept, epic if armored.
