Centaurs
A mythological creature with head, arms, and torso of a human but the body and legs of a horse. Centaurs are known as the kind givers and generally live peacefully though as always, there are exceptions. They mainly roam in the woods were stories are possibly created to scare children and humans away. They are extremely fast and crafty, able to be unseen by the humans for centuries. They extremely dislike Dullahan due to the Endless Wars.
_Dragons
Known as the Gods of Mountains, Dragons generally have a superiority complex. They believe that strength is everything and those with nothing to give are useless. They vary from in structure and abilities but their hierarchy is absolute. Through evolution, they are able to transform and look almost like humans with a few exceptions. They are known to hate Griffins but are pleasant around every other creatures. Believe it or not, Dragons are easy going and likes to fool around yet only serious when situation needs them to be. Although seeming unlikely, Dragons are possibly one of the most patient and gullible mythical creatures around.
Dullahan
Irish dullahan, also called Gan Ceann, meaning "without a head" in Irish, is a headless rider, usually on a black horse who carries his or her own head under one arm. The head's eyes are usually small, black, and constantly dart about like flies, while the mouth is constantly in a hideous grin that touches both sides of the head. The dullahan uses the spine of a human corpse for a whip, and their wagon is adorned with funereal objects or dried human skin. When the dullahan stops riding, that is where a person is due to die. The dullahan calls out their name, at which point they immediately perish. You can't stop the dullahan, nor block the road against a one – all locks and gates open to them when they approach. They do not appreciate being watched while on their errands, throwing a basin of blood on those who dare to do so (often a mark that they are among the next to die), or even lashing out the watchers' eyes with their whips. They are frightened of gold, and even a single gold pin can drive a dullahan away.
Elves
Elves are cordial, friendly, and pleasant to be around. They're expert archers and are considered as the Conquerors of Forests. Elves are praised due to their eyes that could see from unimaginable distance and the accuracy of their arrows. They generally blend in very well if they hide their pointy ears but usually they live far away from humans as possible. Elves are graceful creatures and tends to dislike anything that they consider "ungraceful". However, they are long rivals with Fairies and seemingly have a strong distaste for Fairies as well.
Fairies
Fairies are friendly at heart though many range from being pranksters to being prim and proper. They live mainly in forests and possibly the reasons why Elves despise them so much. Fairies are probably the smallest of mystical beings yet the speediest due to their lightweight nature. Most hate the Elves for hating them but some are generally easy going and what not.
Griffin
Proud creatures of the Sky, Griffins are prideful and strong. They are quite family oriented and domineering as well. Griffins, much like Dragons, could transform to look human-like as they wish. They're quite competitive yet at the same time, the "big brother" type. Their personality ranges depending on upbringing but most Griffins quite tough on others with high expectations. Griffins believe they are the strongest, contradicting what the Dragons believe thus the reason why they have a long term feud ever since...forever.
Harpies
The Angels of the Sky, Harpies are almost as fast as Fairies but not there yet. They are beautiful winged bird-like creatures that also may or may not hunt on innocent men. Harpies are known to be vicious, cruel, and manipulative. There are many female harpies and not much males thus this race is quite matriarchal. Harpies are quite possessive with their men. Once they find their consort, they never let them go. Harpies hate Sirens, maybe due to envy that Sirens do attract more males. Nevertheless, the Ancient Feud still goes on even today.
Phoenix
Known to men as immortal birds, Phoenixes could actually take on human forms. Phoenixes are known for their rapid healing powers and their immortality. However, they are not actually immortal but rather they can regenerate any part of their limbs that has been cut off. Their innate healing powers are most of their specialties with a few special ones able to wield other abilities as well. A phoenix's biggest weakness is that they cannot regenerate their head. Their blood could also heal the injured but only once which is why many phoenixes are hunted and live in isolation in Volcanoes. Most are hot tempered and quick to anger but once in a blue moon, you might see a easy going phoenix. As fiery as their wings, they have a one sided hatred for harpies for unknown reasons.
Sirens
The beauties of the sea, Sirens are known for their beautiful voices that captures even the most willful men. As legend states, Sirens are mainly beautiful man eating mermaids that prey on innocent men. Vicious yet lovely, they're the reason why humans have been so careful in the seas. They are strong and willful, dubbed as the Royalties of the Water. They're fastest in water and it's rare to see one ever on land. They hate Harpies due to the Ancient Feud that caused the closest of friends turn into bitter enemies.
Vampires
Bloodsuckers, vile, and cruel, vampires are known in books as either brooding or sparkly. They are creatures that most resemble humans and could blend in almost perfectly. This is the reason why they have been hunted down in the human dominated society. Vampires no longer exist from the mass genocide started by the human experiment but maybe...just maybe a few remains. Like many mystical beings, Vampires have the super strength, speed, incredible healing capabilities, and god given bodies.
Werewolves
Werewolves, like Vampires, could blend in with the humans quite well except on a full moon. They are generally very clan-like and hunt in a pack. Fast and ferocious, not many wants to mess with them due the fact that werewolves are never alone. Like many other mythical beings, werewolves are also admired for their self-regeneration. Their lands are marked though quite a few live peacefully among the humans. Werewolves and Vampires have a long history together as their hatred started way before the Ancient Feud.
