Warm light from the chandelier spills across the marble floor, painting shifting shadows on the velvet-draped walls. Guests draped in silk and jewels murmur in small clusters, but their voices fade into a distant hum as you step inside, your hand securely held in Nightmare's.

Ready to be admired, you?"
