What Makes a Horror Setting Work?

After reading Chaosium’s Sutra of the Pale Leaves, I found myself returning to an earlier campaign book: Berlin: The Wicked City. Both are ambitious and filled with imaginative potential. But only one of them made me want to run a game as soon as possible.

That contrast got me thinking more deeply about what makes a historical horror setting actually work—what makes it feel alive, charged, and unsettling in a way that makes a great play of Call of Cthulhu.

I have already discussed the relative merit of different historical settings in here. This article will focus on the differences between a setting book about 1920s Berlin and another about 1980s Japan. You don’t really need to know the books to follow the article. And spoilers are kept to a minimum.

When Horror Emerges from History

Berlin: The Wicked City succeeds because it doesn’t really invent horror. The Weimar Republic is already a world of political instability, cultural upheaval, economic trauma, and moral ambiguity. The dark spiral that will lead to Nazism, genocide, and millions of dead is beginning to slowly wind towards catastrophe. Real historical movements, theosophy, spiritualism, secret societies, give it occult depth without needing to invoke the supernatural at all. The excess, the unbridled hedonism that goes along with desperate poverty and social tension are powerful forces. The horror grows organically from lived tensions and unresolved historical trauma.

Every story there feels like it could spiral into madness even before an Eldritch creature appears. The horror is not juxtaposed to the setting. It erupts from within it. It is true that the horror in these scenarios has more the mark of Gnosticism than Cosmicism. But this is altogether fitting the time and place. And although the purist Lovecraftian in me protests, such an authentic utilisation of the setting is strongly to my liking. And even if the scaffolding of its supernatural world is not properly articulated, the great thing with Gnosticism is that, the world being an illusion, almost anything goes.

When Horror Floats Above the World

By contrast, The Sutra of the Pale Leaves presents a compelling mythic structure, with powerful metaphysics, a unique antagonist, and a richly imagined conception of horror. Essentially, it recreates the Mythos of the King in Yellow, making it feel fresh again.

But the setting, 1980s Japan, feels oddly disconnected. The horrors of that time and place are never explored: the alienation of the salaryman, the rise of tech-fueled disconnection, post-industrial anxiety, the lingering shadows of wartime shock and guilt, sublimated into pacifism and ecologism, and the urban isolation that would define J-horror in the following decade.

These could have formed a powerful emotional and thematic foundation. But the text bypasses them in favour of an elegant conception that does not ground itself into the setting. 

The curious thing is that pacifism is easy to associate to the Mythos of the King in Yellow: in all its versions I know, what comes with the arrival of  the King is peace. A peace that is paid for in a surrender of the will. One of the scenarios of the Sutra does gesture towards this dilemma, but it does not embed it sufficiently in the scenario, and it is a surprise when it suddenly appears.

There are other issues with the book, which have little to do with the choice of setting: the scenarios don’t make the most of the book’s proposed Mythos and instead lean heavily on unrelated Japanese folklore for colour, but I’ve written about that elsewhere.

Do You Even Need a Setting?

Some argue that horror doesn’t require a richly embedded setting at all. What matters, in this view, is mystery and human fear of the dangerous and the unknown: What’s in the dark? Why did this happen? Who or what is behind it? Suspense is driven by not knowing, and when the questions are finally answered, the story pivots into action or drama. In this framework, whether the story unfolds in a medieval village, a derelict spaceship, or 1980s Tokyo doesn’t matter. The setting is just a stage.

There’s truth to that. Horror can function without historical or cultural grounding. You can terrify players with mystery, a hidden predator, or isolation, no matter where or when you place them. Human instincts and emotions remain the same.

But the Right Setting Changes Everything

Yet, there’s a difference between horror that simply works and horror that resonates.

Horror may be about emotion at its core, fear, disorientation, powerlessness, but the right setting intensifies those feelings in crucial ways:

1. It makes the horror feel real. When fear emerges from real historical pressures or cultural anxieties, it’s not just scary but plausible. 
2. It gives the horror meaning. A setting can transform abstract dread into thematic expression. The horror becomes not just frightening, but about something: about repression, about decay, about control, about the collapse of order. 
3. It illuminates and increases our understanding of the setting. Through RPGs I have learned much about the particular anxieties and dilemmas of places and times I barely knew before. And through that powerful superposition of supernatural fiction and fact, a deeper understanding of the human condition and society can be attained.
   
   

This is why Berlin works so powerfully: the horror doesn’t need to be imported. It’s already there, in the politics, in the culture, in the madness of the era.

The usage of the setting in the Sutra, on the other hand, feels like a regionalisation. That is, you add specific regional markers to a story that don’t contribute anything to the story in itself. The result is somewhat inert: setting and plot live side by side, but don’t enhance each other.

The usual scholar of a Lovecraftian mystery is replaced by a calligraphist - but is there something about calligraphy that makes the character unique? Does anything change if the man has any other profession? The second scenario is in the world of indie Manga. Again, replace the setting by any other community of artists, it doesn’t even have to be of indie artists or part of a  geekdom, and the adventure can be run largely unchanged. In the last scenario, change the appearance of the monsters to something more culturally appropriate and again the plot is easily adapted to another setting with hardly any loss of poignancy or meaning. Try to do the same with Berlin, and see how much is lost. 

So What Makes a Horror Setting Work?

Some campaigns thrive purely on atmosphere. Others succeed by building intricate mysteries. But for horror to truly take hold, for it to feel meaningful as well as terrifying, it needs more than an unknown entity or an eerie tone. It needs emotional weight.

Horror doesn’t require historical grounding. But when horror emerges from the emotional truth of a particular time and place, it doesn’t just frighten. It resonates.

Post Scriptum: What If the Sutra Were Set Elsewhen?

Reflecting on all of this, I can’t help but wonder whether The Sutra of the Pale Leaves might have landed more powerfully if it had chosen a different moment in Japanese history. The 1980s offer a backdrop of alienation, economic pressure, and technological unease, but they lack the raw metaphysical rupture that fits with the existentialist themes present in the mythos of the Prince. 

In contrast, post-war Japan, the late 1940s and early 1950s, feels almost tailor-made for a campaign about the Sutra. This was a society living through existential collapse: the Emperor revealed as mortal, cities in ruins, gods seemingly absent. The trauma of Hiroshima and Nagasaki introduced a horror too vast to explain through ordinary means. Occupation imposed a new metaphysical order while suppressing older spiritual truths. It was a time of silence, shame, cultural loss, and ghostly survival.

In that setting, the Sutra of the Pale Leaves could have emerged as a forbidden scripture: a cracked lens through which to reinterpret the disaster. The horror wouldn’t need to be justified; it would simply rise out of the ash. The search for a new emperor. The need  for a new personal and social identity. The Sutra’s mythos would feel more grounded, the appeal of the Prince/King much stronger. Post-war Japan was much more vulnerable to a “Saviour” than 80s Japan, more iconoclast and more cynical of political power. The mythology would echo lived pain. And a campaign would ask a deeper question: not just “what is happening?”, but what is there to do once our world ends.
