Diamond Twisters are closed species.
Meaning you can not make your own without my permission.
Diamond Twisters are human beings with animal characteristics, like ears, tails etc.
They are born out of big gemstones that have absorbed a certain life form.
Afterwards when the gemstone has been shartered and the Diamond Twister is born, there are crystals that are perfecly shaped, like diamonds, and who whill start to twirl around the new born DT, this can be the tail, horns, hand etc. These 'diamonds' are attached to the tail and can't leave it unless the DT wishes for it.
After the awakening a diamond mark appears somewhere on their body
