Yet amid the carnage, a single hedge fund and its charismatic, bizarre founder stand proud, reaping rewards while others are crumbling all around them. Now, an intrepid team of investigators, drawn from all walks of life, from financial journalist to concerned dilettante, set out to unravel the mystery, only to find that it runs far deeper and darker than they ever could have suspected.

Athenaeum Illuminatus
Peter Charron ($11.95, 110 page PDF)

Libraries are Illuminated. In many investigation settings libraries are cast in a passive role. They serve as scenery to set a mood or simply as a backdrop against which other action takes place. But libraries can vary dramatically depending on their type and are more than a place to keep books. They are centers of learning, statements of political power and repositories of new, ancient and terrible secrets. They can easily take center stage.

Living Secrets - a Zgrozy supplement
Marek Golonka, Keith Mageau ($1.49, 8 page PDF)

Certain cosmic truths are so fundamental to the fabric of reality that their mere accumulation in one place calls into existence a being that’s more than a mere fact. A Living Secret may be the knowledge of the secret names of the Outer Gods, but it may also be the truth about how life works at a level so deep that earthly biology will not discover it for centuries.

Into the Gothic - a Zgrozy supplement
Maria Borys-Piątkowska, Aleksander Grabowski, Marek Golonka, Keith Mageau ($2.99, 16 page PDF)

Interestingly, Lovecraftian “sanity” is a reflection of the fundamental element of gothic horror—insanity or madness. However, it needs to be said that while Lovecraft described the loss of sanity when one encounters alien forms incomprehensible to the human mind, in gothic horror, it was commonly the result of the awareness of the binary nature of the human condition and the discovery of the existence of evil within himself.

Guide that helps you run Call of Cthulhu games using motives straight out of a Gothic novel.

Sisters of Doom - a Zgrozy supplement
Marek Golonka, Keith Mageau ($1.99, 10 page PDF)

Re-Animator 2508
Quico Vicens-Picatto ($3.00, 16 page PDF)

The lifeless body of an elder thing has been clandestinely transported from Earth to a secluded area near the star Altair by a covert organization which aims to conduct an experiment to bring him back to life. This location was chosen far from prying eyes and densely populated areas to minimize potential harm in case the experiment goes awry. Hence, to avoid attracting attention due to the near impossibility of constructing a space station or planetary outpost that could go undetected by universe-scanning sensors of the Confederation, the decision was made to acquire a section of a distant space station originally intended to house a powerful deep space telescope. It was there, in secrecy, that the experiment would be conducted.

Players take on the role of the musicians of Morbid Rainbow, a psychodeath metal band who, during an interplanetary tour, arrive at the station precisely when the facilities are being used for a dark and occult experiment.

Garnett Elliott ($3.99, 38 page PDF)

Any necromancer worth their salt will be there . . .Something strange is going on at the 10th Annual International Funeral and Crematory Trade Show, held at the resplendent Tampa Bay Hotel.

Lovecraft’s The Case of Charles Dexter Ward. Though written for Pulp Cthulhu, the scenario can easily be ‘de-pulpified’ for a less hyperbolic experience.
