HPL's BoYS is just one of 30+ books available in PDF as part of the current Bundle of Holding deal (and in fact is included in even the lower-tier offer).

The bundle is available until November 17 -- full details here: bundleofholding.com/presents/Cth...

We went all out with illustrating this book and also wrote a small additional section on Unnatural Places invented by Lovecraft. We think it's the most "purist" depiction of HPL's mythos, since it eschews all details not explicitly mentioned in one of his tales. It's less "gamey" than many versions.

The SRD is extensive (40 Mythos Entities, 20+ rituals, and a bunch of cults, artifacts, and tomes) ... but is just text. People kept asking for an illustrated version to serve as a kind of "Monster Manual" and Grimoire book to go with their Cthulhu Eternal core books. And thus was born HPL's BoYS.

The Open Cthulhu Mythos SRD - Cthulhu Reborn | DriveThruRPG β€œWhat primal, inconceivable source of age-old myth-cycles and haunting nightmares might I be on the brink of uncovering?” Β  IMPORTANT NOTE:Β This PDF contains the text of a full set of game statistics ...

When we released our own open game some years later, we had this resource translated into English ... becoming our Open Cthulhu Mythos SRD. It's an invaluable free resource for anyone who wants to build Cthulhu game material free from IP that may be contested.

I wasn't the only person fascinated by this discussion: the German Lovecraft Association (who produce a German-language game called FHTAGN, amongst other stuff) took it upon themselves to exhaustively map out exactly what elements are 100% Lovecraft (and thus Public Domain) in name and depiction.

The essence of the debate seemed to revolve around the divide between which elements of the gaming version of the Cthulhu Mythos were pure Lovecraft inventions, which were wholesale inventions of game publishers, & which were embellishments by gamer companies of vague hints made in Lovecraft tales.

The Safewords of Cthulhu There has been many interesting things to come out of recent debate over on YSDC about the intersection between Intellectual Property law, the Cthulhu Mythos, Chaosium, BRP, and the Open Gaming Lic…

Although I had no relationship with the individual who released the open rules, I was fascinated by the reasons that were given about why such a thing would be illegal. I blogged about it, including here: cthulhureborn.wordpress.com/2019/06/29/t...

Things kicked off when a previous (crude) attempt was made by someone to build an open Cthulhu-themed RPG; something that triggered a degree of public angst and legal threats from one of the bigger game publishers. It was heated enough that the company PR guy was permabanned from one of the forums.

The origins of this book (we lovingly abbreviate it as "HPL's BoYS") goes way back to an online debate -- or brouhaha really -- in mid-2019 about the copyright status of the various Cthulhu Mythos creatures, tomes, artifacts, and spells which appear in various games.

Our Bundle of Holding deal is steaming along, having just passed 420 bundles (~13,000 books) sold. The deal (link @ end of thread) runs 8 more days.

I promised a "behind the scenes" anecdote for every 100 bundles sold so I now owe two.

Here's one .. about H.P. Lovecraft's Book of Yog-Sothothery.

We rarely use stock art 'out of the box' to illustrate stuff, instead chopping it up and remixing it to make our covers etc. But even so the task of guaranteeing 0% AI content (which everyone wants, including us) is becoming harder as time goes on. We want human horrors (like this), not GenAI slop.

.. not least because, as big users of commercial stock art we've seen how many libraries have been 'polluted', usually with spotty and unreliable labelling of AI-content. Prior to 2022, stock art used to be an easy way to illustrate, now we are forced to 'police' every montage we make using stock.

Lots of folks have had a great time with both Smoke Green and Bottoms Up! and have told us tales of epic gaming moments.

One of the great things about both is that they each have 3 possible Mythos themes and endings. The GM picks one to play each time ... which means you can run it over again.

Four vintage soda labels, in a 1920s style. The four flavours are: Moon Tree Ale, Njamura Pod Soda, Djingula Bean Soda, and Xuin Flower Elixir.

Four vintage soda labels, in a 1920s style. The four flavours are: Moon Tree Ale, Njamura Pod Soda, Djingula Bean Soda, and Xuin Flower Elixir.

But the very best thing about a 1920s scenario based around the cut-throat world of soft drinks was ... inventing some labels for odd vintage sodas (or tonics, historically). These offer amazing prop potential for in-person games ... stick some labels on actual bottles of your player's beverages.

Map of the township of Bolton

Map of the township of Bolton

This was an inspired choice for a number of reasons. The grungy town of Bolton (mentioned by HPL in passing in a few tales, most notably Herbert West: Reanimator) is an interesting counterpoint to the lofty academic vibe of Miskatonic U. We were able to invent a whole new town map for Bolton, too!

When asked to contribute a Lovecraft Country scenario for Cthulhu Eternal, Rachael decided on an unusual locale and theme. Her scenario "Bottoms Up!" is primarily about weirdness in the new soft drinks by a brewery in Arkham's industrial neighbor, Bolton.

"Smoke Green" is a nifty little scenario that blends weirdness (the arrival of a new manufacturer of weird green-smoking cigarettes) with the political intrigue of Arkham's mayoral election. It also presents a challenge to players whose first solution to everything is "burn it down".

As part of the vibrant programme of Lovecraftian RPG sessions at the con, I ran two sessions -- one was the scenario that became "Smoke Green", the 3rd in our Lovecraft Country scenario series. Written by the talented Noah Lloyd it was a big hit when run on the top floor of the jazzy Biltmore Hotel.

Text of a poem titled "Halloween in a Suburb", written by H.P. Lovecraft in 1926. The black text is surrounding by an orange glow and there is a creepy hound-like monster lurking in the bottom-right. 

The poem text is:

The steeples are white in the wild moonlight,
And the trees have a silver glare;
Past the chimneys high see the vampires fly,
And the harpies of upper air,
That flutter and laugh and stare.

For the village dead to the moon outspread
Never shone in the sunset's gleam,
But grew out of the deep that the dead years keep
Where the rivers of madness stream
Down the gulfs to a pit of dream.

A chill wind blows through the rows of sheaves
In the meadows that shimmer pale,
And comes to twine where the headstones shine
And the ghouls of the churchyard wail
For harvests that fly and fail.

Not a breath of the strange grey gods of change
That tore from the past its own
Can quicken this hour, when a spectral power
Spreads sleep o'er the cosmic throne,
And looses the vast unknown.

So here again stretch the vale and plain
That moons long-forgotten saw,
And the dead leap gay in the pallid ray,
Sprung out of the tomb's black maw
To shake all the world with awe.

And all that the morn shall greet forlorn,
The ugliness and the pest
Of rows where thick rise the stones and brick,
Shall some day be with the rest,
And brood with the shades unblest.

Then wild in the dark let the lemurs bark,
And the leprous spires ascend;
For new and old alike in the fold
Of horror and death are penned,
For the hounds of Time to rend.
