MY WORLD
Vampires: There are several breeds. The general rules are; they all burn in sunlight, they can't bleed or blush, they have no heart beat, they're room tempreture (the same tempreture as their surroundings) so they seem cold. They turn eachother through biting, the bitten person is injected with "venom" and they die. Their bodies use their blood to convert them. They're bodies break down human blood to heal themselves and give them longevity and energy and power. Their bodies can store the blood until they need it. Also all locks unlock for them and they can walk silently with no sound at all. We will probably only use one:
Pluto: Fire's breed of vampire can last four hours in sunlight. They can breed with non vampire creatures. They are the strongest of the vampires. Their fangs are not retractable. They have trouble hiding them. They have red, steel, or violet colored eyes.
Dracula: the oldest type of vampire. They have retractable fangs. They can turn into bats. They can only breed with other Dracula vampires. They only have red eyes.
Werewolves: They can change into a wolf whenever they want. The can breed with wolves and human or humanlike creatures. They are often in packs. Unlike popular belief, werewolves and vampires are allies. Vampires join werewolf packs often. They love vampire against werewolf stories. That's why they're popular. Packs are small 6-7 members in each with a lead male and female who are mates. They are forced to turn into a terrifying wolf beast every full moon. They'll attack any creature with a heartbeat.
Witches: All witches are against vampires. They are enemies. Witches are exclusively female. Their is only one male witch in the world and he is half vampire (and a character of mine I will bring in later). They can use magic. They look like normal humans. They either choose to use black magic (obtain through evil rituals/means) or white magic (using nature)
Angels/dark angels: don't really come from heaven. They are simply humans with black or white wing (can have both). They are very kind.
Demons: evil creatures that take the form of anything and feed on souls. They appear as very attractive humans. They have a demon form though that is horrible. (Vampires and werewolves are said to also be types of demons).
Dragons: used to be giant winged beasts. Used magic to take on human forms. They only give birth every three hundred years and never die. They cannot be killed. The collect what ever they want obsessively. They seem to be hoarders. They have colored wings of what color they were in dragon form and curled fangs. (Of course if they were a wingless dragon the won't have wings as a human.) They can never turn into a dragon again unfortunately.
Unicorns: Horse; appear as a normal horse but on full moons change into the typical unicorn (and they can talk). Human; they are usually a very fair beautiful person who are extremely kind. They have flawless skin. Unicorns are hunted by witches.
Hunters: humans who inject themselves with dragon blood. They hunt magical creatures to kill them.
The Soulless: Humans who sold their souls. Have black eyes.
Humans: Most are totally oblivious to this world. They believe they are the only creature. The don't live very long but breed very fast.
Special Humans: Humans with powers (ie: telekinetic, elemental, etc.)
Mixes: Pretty much they are mixes of two creatures. They get the powers of both parents. Creatures that can't be mixed are; Dracula vampires, demons, dragons, unicorns, and the soulless. They age to the peak of their young life (usually 16) then stop if they're immortal. If they're a mix of two human creatures then they don't stop aging like humans.
