Silas Marsh has loved the sea ever since he was old enough to toddle through its briny shallows. Becoming a sailor was the easiest decision he ever made, and his sturdy frame and excellent sense for the weather have given him a good reputation aboard any vessel. There is only one thing troubling Silas: over and over again, he dreams of unsettling cities hidden beneath the waves and inhabited by bizarre creatures. These dreams call to him, stirring something deep within him that he thought he had left behind in his hometown of Innsmouth.
