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)

Lurking within lies a creature older than mankind itself, dreaming of its release…

1920s scenario that offers a twist on the typical horror scenario, by challenging the players to think not only creatively, but also morally. This scenario subverts the investigators' expectations by presenting no conventional "monster" to defeat, only an encounter with a mind-bending and incomprehensible creature, whose fate is left in the hands of the investigators.

Operation Midnight Sun
Chicho Ocariz "Arkashka" (Pay-What-You-Want, Rec Price $3.99, 27 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.

This solo scenario takes place at a CCC worker’s camp during the Great Depression. Investigators will face many horrors as they try to uncover a disturbing mystery surrounding the mountain from which the camp gets its name: Dead Man’s Peak. To reveal too much about the story behind it would be spoiling the discovery that will happen organically within the scenario, but suffice to say that investigators will be tested to the utmost.

If you enjoyed the Solo Investigator’s Handbook, and would like something a bit more fleshed out by the same author, then this book will provide what you’re looking for - an immersive solo experience where your investigator is dropped into danger and pitted against forces beyond their control!

Ectoplasmorphia
Hyacinth (Pay What You Want, 20 page PDF)

Ectoplasmorphia is a one-shot scenario set loosely in the United States in 1926. It focuses on two very different households and the ways in which these interact with the people visiting them. Being chased through a forest will result in them having to pick sides at a crossroad: each path leads to either a house to the left or one to the right, and as they’re about to find out upon exploring, these are both corrupted, and won’t take so kindly to intrusion.

One shot set in the seedy underbelly of the most cosmopolitan city of the early 20th century - a city where a fistful of dollars sufficed for a visa, a shotgun barrel sufficed for negotiation, and a mish-mash of overlapping international jurisdictions sufficed for governance.

Tomes of Eldritch Lore - Expanded
Peter Charron ($12.99, 72 page PDF)

Rare is the scenario which doesn’t involve, or at least name-drop, a Tome of Eldritch Lore. Encountering them is always a two-edged sword, bringing investigators excited anticipation and a sense of foreboding. Weighing power at the risk of madness, they almost always peek inside the covers. Too often, they might not have a choice. This resource greatly expands on the tomes listed in the Keeper’s Handbook. Each comprehensive entry includes publication date, language, author, editions, and translations. Included is a physical description, binding materials, topical contents and historical information about the work and author. The Game Statistics portion offers base study times, Mythos percentiles, Sanity Loss and more. Most profiles include an image of the book’s binding or frontispiece.

Codex Alchemica
Peter Charron ($14.99, 110 page PDF)

Since it emerged in ancient Egypt and China 2,300 years ago, scholars have pursued the potential of Alchemy. It is an Art that combines opposites and channels natural philosophy, chemistry, astrology, mysticism and magic into a single cohesive discipline. Although its methods have changed over the centuries, the goal has always remained the same: transmutation.

The Codex Alchemica provides the Keeper with a suite of new tools to adapt and incorporate alchemists, their compounds and tomes into Call of Cthulhu investigations working within the existing Seventh Edition framework of magic. The Codex also provides a wealth of world building and plot inspirations. It serves as a robust resource, and also a jumping off point into further research into this deep, endlessly fascinating topic.
