Nyx Queen of Darkness
The museum owner pulls you to the side to speak with you. "Terribly sorry about that whole locked-in-the-museum-overnight thing. If you were involved in that misunderstanding we'd like to give you a complimentary gift provided you'll sign these non-disclosure agreements.. You may choose one of the items from our Gift Shop for free."
Also signs NDA. The museum really is lovely, but next time I will visit in the morning
