H. P. Lovecraft's The Shadow Over Innsmouth introduced us to a corrupt and fallen town, owned and controlled by the dark Esoteric Order of Dagon. But how did Innsmouth fall so far from the healthy New England town that it had been? What could possibly convince an entire port town to abandon their beliefs and morality for the darker path of the Necronomicon?

The answer was found in the lost journals of Obed Marsh. This is the tale of how a man, devout in his Catholic beliefs, could be corrupted and torn from grace. This is the explanation of how he took all of Innsmouth with him. This is The Trials of Obed Marsh.
