Welcome to tonight's Delta Green operation. The year is 2019, and our scenario takes place in the remote coastal town of Blackwater Cove, Maine. A series of disappearances has caught the attention of the Program. Locals blame natural causes—undertows, rip currents, the dangerous rocky coastline—but something about the pattern has raised flags. The victims' bodies that have been recovered show peculiar biological anomalies: strange markings resembling glyphs beneath the skin, microscopic organisms never before cataloged, and impossible decomposition rates.
