The glaistig is a solitary fey creature that feeds on blood. It appears as a beautiful woman, often with long blond hair, that has the lower body of a goat. The glaistig will conceal her goat nature with long, flowing robes.
While a glaistig may prefer to live near water, it isn’t bound to a body of water, and may prefer to live in a cottage. The glaistig will probably still choose to be close to a body of water simply as a means to escape should it be attacked by a strong foe.
Blood Drinker. The glaistig drinks blood, predominantly from mortals it lures with song, dance, and the promise of romantic liaison. It will attempt to isolate its prey before making its attack. Once disabled, it will slit the victim’s throat and drain it of all its blood.
Protector of Herds. The glaistig isn’t always malevolent, and can be benign when properly treated. It is protective of herded animals such as cattle, goats, and sheep, and the herders who tend them. The glaistig can be placated by a herder with an offering of milk each morning. So long as this arrangement is met, the fey will watch over the herd from afar.
Traveler’s Bane. At times, the glaistig is less deadly in its malevolence, opting to use its powers to misdirect and confuse travelers in its domain. The glaistig may simply aim to leave travelers lost in the wilderness, but might also lead the travelers to the domain of another creature.
The Green Maiden. Legends tell of a woman who met with a violent end and was abandoned who transformed into a glaistig known as the Green Maiden. Often she is depicted as benevolent, watching over mothers of newborn babies. The Green Maiden can be appealed to for mercy, and may even enter a pact with a prospective warlock.

Beguiling Performance. The glaistig sings or dances. Each creature within 120 feet that can hear or see it must make a DC 15 Wisdom saving throw. On a failed save, the creature is charmed by the glaistig for 1 hour. It will use its movement to move toward the glaistig each turn. While charmed, the creature will not defend itself from the glaistig’s attacks. At the end of each of its turns the creature makes a new saving throw.
