The nightmare queen is married to King Finvarra. Because they are no longer on speaking terms, she has moved her court to the new world.

She has sworn an oath never to attack anyone herself, and has used that oath to obtain the power to shape oaths sworn before.

When receiving gifts, she prefers to receive Oaths sworn before her. The stronger the oath, the greater the gift. Alternatively, she likes to receive mortals with unique qualities or aesthetical value.
