The nightmare queen is married to King Finvarra. Because the couple is no longer on speaking terms with each other, she moved her court to the new world. She usually holds court at Chinon Castle, where she received guests and delegations.

Among the oaths she has sworn is an oath to never attack anyone herself, which she has used to obtain the power to shape oaths sworn before by others.

It is a well-established tradition that, in exchange for her hospitality, guests bring with them a gift. 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.
