Plague of Frogs


The Plague of Frogs is an adventure/mystery for Liminal Horror that has the players investigate a rash of attacks that have end up being more than random bouts of violence. Can they stop the Plague of Frogs without fracturing their minds & bodies?

TOUCHSTONES: BPRD: Plague of Frogs (comic) Re-Animator (film) Aliens(film)

Mystery Structure: This is the first text using Liminal Horror's new mystery structure (so you too can create your own).

  • Concept & Touchstones: (using film/comics/novels or just specific scenes/images can help anchor the creative process)
  • Factions & Their Goals: Helps ensure that actions and reactions can take the vying agendas into account.
  • Doom Clock: A baseline sequence of events that would happen if the investigators do nothing. This framework changes in response to  the player's actions.
  • Hooks: A sample list of examples how to entangle players. The choice depends heavily on the decisions made in character creation (and The Party). 
  • Potential Clues: A nonexecutive list of potential clues that players can discover. These are like the index cards/red string in a pin board. Think of ways to connect the anchors (victims, event, malefactor) and the crime framework (means, motive, opportunity, next move). The great thing is you don't need all the answers ahead of time, they will emerge in play and in what makes sense.
  • NPCs: A list of important NPCs with their stat blocks. I also include potential types of people the investigators may encounter (so you can be prepared  ahead of time if that your preferred route.
  • Locations: A few important locations detailed. Many scenes take place outside of these places but these are where many of the factions reside.


  • Liminal Horror is a modern cosmic horror hack for Cairn and can be found on DriveThruRPG.

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.
