Empire Nox runs an adults-only night for couples and single women, under the line 'a night beyond desire'. The organiser describes a world behind closed doors built on tension, attraction and seduction — a night meant to be sexy, stylish and daring, for people who are open-minded.

Its format is The Playground, which it describes as a game of desire and seduction with its own map: guests start at a central point called The Main Game and choose a route through rooms including The Red Lounge, The Exclusive Zone and The Hidden Floor, unlocking further play rooms as the night goes on. Some rooms go dark completely; others let guests watch from behind glass.

The house rules are published in full and are unusually explicit. Entry is for guests aged 18 to 40, with physical ID possibly required at the door. Couples means one man and one woman; single women are welcome and single men are not admitted. A couple enters together and leaves together, and if one partner goes home so does the other. Consent is stated as a standing requirement — yes means yes, no means no, silence is not consent, and being inside Empire Nox is never consent by itself.
