Very old money was behind the Crow's Nest. And enough of it that its Owners didn't mind losing some every month to keep the place going. It was a kind of eleemosynary institution, created to serve not culture and not dukh, but a thing called the Purpose. And if Ty kept working there for another few decades, perhaps one of the Owners would sit him down one day in the Bolt Hole and deign to tell him what exactly the Purpose was.
