The Trials of Obed Marsh
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?
This is the fall of Innsmouth.
