Deep in the waters of Silvershore lies the City Beneath, home to the city's water-breathing denizens... and an ancient and mysterious monster named Enoch. Enoch, it is said, was present when Silvershore was first built, and so knows every secret the city holds. Sir Tristan the Cold is in search of one secret in particular -- and neither Enoch nor the city they built will survive if Tristan gets his hands on it.
