Curse of the Sculptor

Some elves have done such insane evil that they chose to forget their names. One of these was nicknamed simply "The Sculptor." He believed that elves should improve themselves, and not wait for salvation from the outside. The sculptor kidnapped people and experimented on them. He dreamed of creating a creature that would combine elven agility with human vitality. He sewed animal bones into flesh, mixed elven blood into veins, fused tendons. And one day it seemed to him that he had almost succeeded.
 
He took a young man with strong shoulders and decided to make wings out of his hands. The sculptor transplanted additional limbs from the people he killed, fused them with shoulder blades and applied elven magic to them.
 
But the experiment went wrong. The consciousness of the subject could not stand the pain: he did not become an ideal warrior, he became a dangerous insane monster with wings in the form of hands. The creature broke the chains, killed the Sculptor and fled to the mountains. It is said that this creature hates every elf in the Sphere. And many of those who still remain try not to go to the north, so as not to stumble upon the creation of their fellow tribesman.
