The Den was founded by Lupa, the she-wolf who raised the founders of Rome and wanted somewhere quiet afterwards. She built a lobby, hung a bell, and wrote one rule over the door: no drama on Den grounds. Two thousand years later the rule is still there, and so is the bell, which has been rung for every guest who broke it.
Guests come for the Pax Pawmana. They stay for the blankets, the concierge who never asks why you need a dinner for twelve at four in the morning, and the quiet certainty that whoever is in the next room will not start a thread about you before breakfast.
