The Book of Unremitting Horror (GUMSHOE version)


The Book of Unremitting Horror has been nominated in the Best Monsters/Adversaries category of the 2008 Ennie Awards.

A huge GUMSHOE source book for The Esoterrorists and Fear Itself

The Book of Unremitting Horror ... presents a coherent and darkly surreal mythos the equal of Cthulhu or the world of Kult with a full background, albeit jumbled up, based around cults, The Outer Dark, the sinister and incomprehensible Ocean Game and the strange and dark creatures that this otherworld spawns. While it can be used to provide things for the other games I feel that Unremitting Horror is more than just a resource book for antagonists and is worthy of its own devoted campaign of either of the other games.

Flames Rising review

Players in horror campaigns are a little too accustomed to the nightmares their characters face; even the most eldritch of tentacular horrors is less intimidating when you know exactly what it is, because your PC has faced it before.

New times demand new nightmares. This, therefore, is a book of horrors, not a manual of monsters. The horrors are nightmarishly intimate, often created from human vice, or let loose by human greed. They show us the ugliness that underlies reality. They are the crawling things under the rock of the everyday, sane world. Consequently, we've detailed our creatures in depth.

Each one has its own agenda, its own reason for existence and its own legend. We've made these creatures unusual, frightening and bizarre, yet sufficiently comprehensible that they players realize they are up against something intelligent, if inhuman.

The Book of Unremitting Horror includes thirty creature each with:Grinder

  • Diary entries, articles and transcripts
  • A detailed description with behaviour
  • The forensic clues left behind by the creature
  • Details of their history and origins
  • Their special abilities
  • Their GUMSHOE system stats

The Book covers using creatures with The Esoterrorists background, and another includes detailed adventure hooks for use with that setting. There are also artifacts and new GUMSHOE abilities. Finally, the book includes two full length adventures.

Using BOUH with The Esoterrorists and with Fear Itself

In The Esterrorists, you are a highly competent investigator, tracking down creatures of unremitting Horror. You may risk injury, madness and death, but it's your choice. In Fear Itself, your just a normal person, and the creatures are after you.

Let's take an example creature, the Sisterite. She hunts down vulnerable men online, arranges a date, then eats them. In Fear Itself, the adventure might start with your techie friend going missing. In Esoterrorists, you would be part of the OV investigating the a rash of disappearances from a tech support centre.

So on one hand, I've heard a lot of *really* good stuff bout this, I've really liked GUMSHOE, and really, Pelgrane's stuff in general. I feel they've earned the benefit of my doubt, and consequently, wallet.

On the other hand, their example - "the Sisterite. She hunts down vulnerable men online, arranges a date, then eats them" - does nothing to inspire confidence. It strikes me as 80's-style "hurr hurr, chicks are trying to kill you dude" female as evil/alien/other succubus stuff, which is super not-interesting to me.

Which, whatever, I'm not trying to diss anybody's style, or start an argument online (really not that), but it's personally not my cup of tea. What I am, is curious regarding other people's experience with the book, and if the above is a representative sample of the kind of things I should expect inside.

There's a lot of reviews about how great it is, but I'm learning that horror is super subjective. One gamer's classic archetype causes...See more

I know it's been a while since you posted this, but I figured I'd respond anyway since I'm a fan of this book and you probably knew how quiet this section is when you posted.

As the description says, the point of this book is to create original horror creatures for a modern setting, and it shows quite often. Most of the beings are manifestations of/related to the darker sides of (especially urban) society. A creature that preys upon lonely men was an obvious choice, but it was a poor creature for them to offer as a representation of the book, since A) as you mentioned, it hits a little too close to 80's direct to VHS slasher movies and B) it's kind of boring in that it seduces men, eats them and that's about it.

A better example of the spirit they were going for are Ovvashi, a more intelligent (and creepier) being that infiltrates homeless communities and starts turning them against each other by taking advantage of their desperate situations, giving them a taste of the life they once...See more

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
