This isn't really a traditional city supplement. Rather, it's a set of adventure locations and a ready-made web of intrigues to plug into more or less any fantasy campaign (though it dovetails most clearly with Hydra's other campaign setting books, such as Slumbering Ursine Dunes).
It's possible to run it completely straight, but there's a lot of dry humour and the sensibility is strongly coloured by Vance's Dying Earth books. Essentially, if you like Vance's sardonic innkeepers and eloquent ne'erdowells, you'll probably like Marlinko.
