The power to use the abilities of a Nuckelavee. Variation of Fairy Physiology.


User with this ability either is or can transform into a Nuckelavee a malevolent spirit in Celtic myth, that lives mainly in the sea, but was also held responsible for ruined crops, epidemics, and drought. His breath could wilt the crops and sicken the livestock.

The Nuckelavee resembles a centaur whose legs are part fin; he has an enormous gaping mouth and a single giant eye, which burns with a red flame. Some sources describe him as having both a horse's head and a human head and torso, the latter growing out of his back. Arguably the most gruesome detail of the Nuckelavee's appearance is the fact that he has no skin. Black blood courses through yellow veins, and the pale sinews and powerful muscles are visible as a pulsating mass.

When enraged, the Nuckelavee goes on a wild rampage, bringing plague and illness everywhere it goes.

  • Phobia of kelp; a local name for the ash produced by burning seaweed.
