Dearg Due

Vampires! Although they are only female in Celtic folklore, like all the faerie races, there are male and female dearg due in Tír na nÓg.  

In Mythology and Folklore:

The Dearg-Due is a vampire like entity in Irish folklore. Dearg-due, an Irish name meaning “red bloodsucker,” is a female demon that seduces men and then drains them of their blood. The myth is far from cozy, so I won't include it here, but you can find it if you google the term!

From The Books:

The thin, pale cook held out a tin plate stacked with golden pancakes. I reached for it eagerly and then almost dropped it when Calder smiled at me. His wide grin revealed a mouth full of needle-sharp teeth

I gasped and stumbled back a step.

“Ah, Tiernan didn't warn you.” Calder looked down and scooped fresh batter onto the sizzling rock. “My grandmother was a dearg due, but don’t worry, I have no taste for blood myself.” -
