'In April 1936, Lovecraft’s novella The Shadow Over Innsmouth was first published. Written five years earlier, but oddly rejected by every magazine it was ever submitted to, it accurately described a series of events that actually happened in February 1928, when federal government agents raided Innsmouth and attempted to eradicate a deviant race of ichthyoid creatures which had been interbreeding with the human population for decades, if not centuries. Following these startling revelations, the F.B.I. delved into the stories that Lovecraft was publishing as “fiction.” Incredibly, it soon began to emerge that the events in Innsmouth were not a solitary event—and the monstrosities the author described really did exist.

'To combat these cosmic horrors, the Human Protection League (H.P.L.) was established to investigate and combat these otherworldly invaders. Down through the decades since, the only defense that has stood between humanity and these creatures of chaos are the agents of the H.P.L.—or, as they are sometimes known to those few who are aware of their existence: The Lovecraft Squad.'
