Dark Wings

Dark Wings are a rare species of wyverns capable of controlling cursed flames. They are well acknowledged for their swift wing beats and powerful flames, but in truth, they are simply the fallen results of a powerful species of ancient dragon being cursed.

Dark Wings that transcend their limits are said to be able to return to their original form, but not only are there very few Dark Wings, even their fallen forms are so powerful that it is hard for them to reach their limit.
