Much like the Jonstown Compendium for RuneQuest: Roleplaying in Glorantha and The Companions of Arthur for material set in Greg Stafford’s masterpiece of Arthurian legend and romance, Pendragon, the Miskatonic Repository for Call of Cthulhu, Seventh Edition is a curated platform for user-made content. It is thus, “...a new way for creators to publish and distribute their own original Call of Cthulhu content including scenarios, settings, spells and more…” To support the endeavours of their creators, Chaosium has provided templates and art packs, both free to use, so that the resulting releases can look and feel as professional as possible. To support the efforts of these contributors, Miskatonic Monday is an occasional series of reviews which will in turn examine an item drawn from the depths of the Miskatonic Repository.

Miskatonic Monday #389: The Menagerie of Forgotten Horrors
—oOo—
The Menagerie of Forgotten Horrors: A Role-Playing Scenario Set in the Classic 1920s Era is set in New York City and its surrounds in the summer of 1923. It opens in classic fashion a missing persons case, Mary Cobbler being concerned about the disappearance of her younger brother, John. She will alert the Investigators by telegram and then in person, they will learn that of later John has been sleeping poorly, spending time at the local library conducting research of some kind, and had received a letter that he avoided talking about. He has been gone a few days after leaving to conduct his sister thought was more research at libraries in New York. A simple search of his room turns up multiple clues as to his paranoid state of mind, a preoccupation, and some correspondence with a Doctor Edward Huntingdon who like the Cobblers, lives in New York suburb of Greenwich. Unfortunately, by the time the Investigators get to Doctor Huntingdon’s house, he is lying dead in a congealing pool of his own blood, on the floor of his office, his face and the front of his skull missing, as large, black maggots writhe in what remains of his brain!
It is a striking opening scene to the scenario—the earlier interview with Mary is more like an extended cold open—which sets the tone for the rest of the scenario. It is clear that there is something strange, not to say ghastly, going on and it is equally clear that John is somehow mixed up in it. This is confirmed when men come to the house shared by John and his sister and break into search it in the middle of the night. Ideally, the Investigators will be staying there, the default being they are actually based in Arkham, several hours’ travel away in New England, so that the Keeper can run a creepy cat and mouse encounter in the dark of the Cobbler residence. Further investigation upon the part of the Investigators will lead to a farm on the outskirts of Greenwich and into New York itself. There are other nasty encounters too, again with the strange men who broke into the Cobbler house, at a church and then later in a New York warehouse before the plot leads into scenario’s final revelation and climax in an unexpected location, some ‘distance’ from the city. A handful of endings to the scenario are given, at least one of them having a very nasty sting in tale.
So what is going on in The Menagerie of Forgotten Horrors? The scenario revolves around an attempt by a group of occultists and members of an extended family, led by a wealthy industrialist, to lift a curse that has plagued the family for centuries. They are not the villains of the piece though. The villains are the cultists who originally placed the curse and the cultists that now want to keep it in place. There is a pleasing bait and switch here. The occultists and family members and their plans that John Cobbler has got himself wrapped up look like traditional Call of Cthulhu cultists at first, whereas they are merely well intentioned, and of course, misguided, since they are, after all, dealing with the Mythos. The actual cultists, the ones which want to prevent the industrialist and his cohorts from lifting the curse, are the evil, monstrous ones here. Effectively, this is not just a case of a bait and switch between occultists and cultists, but also what looks like cult on cult action. All of which is going to look mighty mysterious and downright confusing to the players—especially if they are veteran players of Call of Cthulhu—let alone their Investigators.
More than half of The Menagerie of Forgotten Horrors is dedicated to supporting the Keeper. The Mythos monsters are surprisingly detailed, and the scenario includes thirty maps and handouts. The scenario also comes with six pre-generated Investigators including a biology professor at Miskatonic University, a private investigator, a journalist and author who writes about the occult, a boxing coach, a historian, and a vaudeville performer. All six come with detailed backstories, but how they are connected to each other, let alone John Cobbler, to come together to investigate his disappearance is a mystery in itself and really, the scenario’s biggest weakness.
Physically, The Menagerie of Forgotten Horrors is very nicely presented with decent artwork and excellent maps and handouts. In fact, there are some thirty maps and handouts, and they are really very good. However, it does need an edit in places. It is decently organised, and each scene ends with the clues and links to other scenes and locations.
The Menagerie of Forgotten Horrors: A Role-Playing Scenario Set in the Classic 1920s Era is a richly detailed, clue dense scenario that takes a classic Call of Cthulhu situation and switches things around to rightfully confusing effect. This is a surprisingly cunning, but well put together scenario.
