Pixie

Encyclopedia Entry:
Though they resemble fairies, pixies are a separate race of fey. They are said to be born from the spirits of dead children. Extremely fond of pranks, pixies delight in humiliating any human who enters their forest.

Pixies are similar to succubi in that they seek to collect the spirit energy of human men. They swoop down en masse on any man who losses his way in the forest, and use the entirety of their small bodies to extract the spirit energy through his semen.

Caution: Pixies will often pretend to be fairies, who are known to be friendly toward humans, in order to lure men into the forest.

Pixies have magic powers proportionate to the amount of spirit energy they have collected. A pixie with a sufficient amount of spirit energy can make herself grow to human size before she attacks. She can also shrink a human man down to her own size and take him away to the world of the fey. Pixies with this level of power should be treated with extreme caution.
