For those of you who want the quick and dirty list, here's what's in this Stretch Goal!

  • Shadows out of Space: Quachil Uttaus
  • Shadows out of Time: Ubbo Sathla
  • Campaign Launch Adventure (PDF)
  • Mythos Cats added to the book
  • FREE Hero Labs Data Files
  • $50 Bonus: High Priest Model
  • $100 Bonus: High Priest Model + Tcho-Tcho High Priest Model + an extra model from each of the Horde Packs

Foulness from the Stars: Brain Cylinders

"There was a harmless way to extract a brain, and a way to keep the organic residue alive during its absence. The bare, compact cerebral matter was then immersed in an occasionally replenished fluid within an ether-tight cylinder of a metal mined in Yuggoth, certain electrodes reaching through and connecting at will with elaborate instruments capable of duplicating the three vital faculties of sight, hearing, and speech. For the winged fungus-beings to carry the brain-cylinders intact through space was an easy matter." (The Whisperer in Darkness; H. P Lovecraft)

NOTE: This image of the Brain Cylinder is a piece of concept art. The final sculpt is not finished at this time.

Brain Cylinders can hold the brain of any sentient being - human, elf and alien alike. Once contained in the cylinders, themselves, the disembodied minds of the original creature become effectively immortal, and can be used with any number of devices, allowing it to see, hear and speak. Mi-go frequently use the cylinders to allow long distance travel for humans - to other planets, or locations in the multiverse. However, other applications and technologies are also available. For instance, it would be possible to craft a cybernetic body for a Brain Cylinder.

When The Great Stretch Goal is funded, we will include a Brain Cylinder model in the Foulness from the Stars Adventure Kit and add details about Brain Cylinders to the book. You will be able to create Brain Cylinder NPCs and cybernetic monstrosities.

More terryinging then losing control of your mind, is having it preserved to watch and communicate with the living!

The cylinder itself is made from earthly materials, and can even be reproduced by humans. The true alien technology is not the cylinder, but the fluid inside. This material is partly biological in origin, partly other-dimensional. It constantly repairs and maintains the healthy state of the brain, preventing deterioration and maintaining permanence. It even prevents diseases and provides effective immortality. The cylinder is self-powered and never runs out of energy – it can keep the brain operating for millennia. It always emits a slight glow, and particles of light can be seen “crawling” up and down the brain and brainstem. The transparent portion of most cylinders is made from armor-glass, and is sword-proof. The Mi-Go have a large variety of devices they can hook up to their cylinders, including means of interrogation and even torture and punishment.

The true horror, and a great secret of the Mi-Go, is that it is as possible to plug in a whole new BODY for a cylinder to control as a simple voice or vision machine. For this purpose, they use bio-chemical-mechanical creations that are partly surgical in nature, mostly organic, and partly cybernetic. Typically the brain cylinder is clearly visible in a clear organic dome on the front or side of the Thing. They are mostly fungus, though with some crab- or spider-like parts, and they can speak mechanically through attached loudspeakers.

Shadows out of Space: Quachil Uttaus

"It was a figure no larger than a young child, but sere and shriveled as some millennial mummy. Its hairless head, it’s unfeatured face, borne on a neck of skeleton thinness, were lined with a thousand reticulated wrinkles. The body was like that of some monstrous, withered abortion that had never drawn breath. The pipy arms, ending in bony claws, were outthrust as if ankylosed in a posture of an eternal dreadful groping." (The Treader of the Dust; Clark Ashton Smith)

This is a photo of the model sculpt, which is still a work in progress.

When The Great Stretch Goal is funded, we will include a Quachil Uttaus model in the Shadows out of Space Adventure Kit.

The Treader of the Dust, from Clark Ashton Smith’s eponymous story, is a terrifying demonic entity. Beware even reading his summoning formulae, for he may appear.

Shadows out of Time: Ubbo Sathla

"For Ubbo-Sathla is the source and the end. Before the coming of Zhothaqquah or Yok-Zothoth or Kthulhut from the stars, Ubbo-Sathla dwelt in the steaming fens of the newmade Earth: a mass without head or members, spawning the grey, formless efts of the prime and the grisly prototypes of terrene life... And all earthly life, it is told, shall go back at last through the great circle of time to Ubbo-Sathla." (The Book of Eibon; Clark Ashton Smith)

This is a photo of the model sculpt, which is still a work in progress.

When The Great Stretch Goal is funded, we will include an Ubba Sathla model in the Shadows Out of Time Campaign Collection. Now you have the creature that guards those items important to the horrifying gods of the Cthulhu Mythos.

The primeval being placed upon Earth to guard the Tablets of the Gods.

Campaign Launch Adventure

"While my chosen form of story-writing is obviously a special and perhaps a narrow one, it is none the less a persistent and permanent type of expression, as old as literature itself. There will always be a small percentage of persons who feel a burning curiosity about unknown outer space, and a burning desire to escape from the prison-house of the known and the real into those enchanted lands of incredible adventure and infinite possibilities which dreams open up to us, and which things like deep woods, fantastic urban towers, and flaming sunsets momentarily suggest." (Notes on Writing Weird Fiction; H. P. Lovecraft)

This is an adventure designed specifically for introducing players and characters alike to the Cthulhu Mythos. Written to be used with characters of any level; we’ll include multiple challenge rating choices for Game Masters, so that they can tailor the challenges to the adventuring party. This gives your gaming group the benefit of being able to roll up new characters or have existing characters at a higher level enter into the adventure. Additionally, it is ‘world neutral’ so it can be dropped into any world setting. Lastly, it allows you to use the great miniatures you’ve purchased from this Kickstarter!

We have a couple of things up our sleeve for this adventure that I'm really excited about! Anyone who's ever ran in any of Sandy's adventures knows that he has great ideas!

Mythos Cats

"It was a stupendous sight while the torches lasted, and Carter had never before seen so many cats. Black, grey, and white; yellow, tiger, and mixed; common, Persian, and Marix; Thibetan, Angora, and Egyptian; all were there in the fury of battle, and there hovered over them some trace of that profound and inviolate sanctity which made their goddess great in the temples of Bubastis. They would leap seven strong at the throat of an almost-human or the pink tentacled snout of a toad-thing and drag it down savagely to the fungous plain, where myriads of their fellows would surge over it and into it with the frenzied claws and teeth of a divine battle-fury. Carter had seized a torch from a stricken slave, but was soon overborne by the surging waves of his loyal defenders. Then he lay in the utter blackness hearing the clangour of war and the shouts of the victors, and feeling the soft paws of his friends as they rushed to and fro over him in the fray." (The Dream-Quest of Unknown Kadath; H. P. Lovecraft)

There are different variants of intelligent cats throughout the Cthulhu Mythos. There are Dreamland cats, cats from Saturn; it has even been proposed there are different cat races from every planet in the solar system. There is no knowing how many subspecies of cats exist on planets and moons throughout the multiverse.

After funding The Great Stretch Goal, the book will include everything you will need to know to play a cat as a Player Character race. Additionally, we will include different Mythos cat races to use as your Player Character race or as a the foundation for creating your own.

Sandy Petersen's Cthulhu Mythos for Pathfinder would be cosmically unbalanced if it had rules for playing a Zoog as a PC race and didn't have rules for playing their arch nemesis cats, too. Not only can Mythos cats be "furry" fun, they can also be scary and powerful entities with inter-dimensional abilities and diabolical intellect.

Hero Lab Support

You asked about Hero Lab support. Based on the survey we ran, we found someone to make your requests a reality!

Every backer that receives the PDF or hardback of the book will also be able to claim a code allowing them FREE access to the Hero Lab data files for Sandy Petersen's Cthulhu Mythos for Pathfinder.

Don't have Hero Lab? Fear not. If you add $30 to your pledge, we'll also issue you a Hero Lab license alongside your data files. And since Hero Lab comes with one additional choice of game system, you can choose the Pathfinder Roleplaying Game and have everything you need to make Cthulhu Mythos creatures using Hero Lab.

Bonus for $50+ Backers

If we fund The Great Stretch Goal, every backer that pledges $50 of more will receive one FREE High Priest model.

Bonus for $100+ Backers

If we fund The Great Stretch Goal, every backer that pledges $100 or more will not only get a high priest model, but also a FREE Tcho-Tcho High Priest model.

In addition, every backer pledging $100 or more will also receive one additional model from each of the Horde Packs (Cultist, Deep One, Mythos Ghast, etc).

      "more capable versions"
      Butt-licking notwithstanding. ;)

      1) Generally, no. They are intelligent beings, making them available as cohorts via the Leadership feat. Some cats barely qualify as 'intelligent', and may qualify as animal companions, but our focus will be on the... more capable versions.

      2) Of course. We already planned to do that.

      As a Kickstarter backer and player of the cat-based Call of Catthulhu ( ), I now feel like I need to acquire this book. Well played.

    4. Philip Alexander Dale on April 1, 2016

      I'm glad to see that the cats from Saturn are getting some love! :D

      I have two questions:

      1) Will cats and zoogs still be able to be familiars/companions?
      2) Are Ubbo-Sathla and Quachil Uttaus going to get corresponding articles in the book?

      The idea of cat customization is absolutely amazing and inspired (the spindly, multi-legged cats from Uranus mentioned in your guide to the Dreamlands come to mind), so even if cats for every planet in our lowly solar system seems a bit of a stretch I'm not complaining ;) .... Wait a minute, does this mean that there are cats native to Yuggoth on the rim?? O_O

    5. Thomas on April 1, 2016

      Dang. Understandable. I was really hoping this update was going to provide a sample adventure, so I'm not too disappointed. :)

      Thomas, we're not planning to print the adventure at this time.

    7. Thomas on April 1, 2016

      Would it be possible to have an add-on of a physical copy of the starting adventure?

    8. Arthur Petersen Collaborator on April 1, 2016

      Hahaha yes, The only thing that is not physically added to the book that his book related in this stretch goal, is the adventure

      Opps! Apparently I misread the update... forgive me I haven't finished my coffee this morning!

      I'm excited to see the addition of the launch campaign but bummed that the cats as a playable race is only available from download. I'd much rather increase my pledge by $30 if it were added to the physical copy of the book.

    11. Valentin Wake on April 1, 2016

      I just said that there is more minis' related. I'm really happy about the adventure and the other rules addition (I won't use hero lab), I was just saying that there was more minis content than rules content in the stretch goal. Of course I understand that the adventure is a huge task. It wasn't meant as a criticism.

    12. Sandy Petersen 19-time creator
      on April 1, 2016

      @Valentin all you can see is more minis? We added a whole new PC race, Hero Labs, brain cylinder rules, and an adventure.

      @Jason Seal
      the brain cylinder miniatures are part of the Onslaught 2 counter add on set

    14. Luke Murthwaite on April 1, 2016

      @Jason Seal the Brain Cylinder minis for Cthulhu Wars (32 of them) are being included in the Shining Trapezohedron add-on pack from the OS2 campaign. Check update #68 ;)

      Jason Seal on April 1, 2016

      Will we be able to get brain cylinder miniatures for Cthulhu wars?

    16. Luke Murthwaite on April 1, 2016

      I'm not sure what you mean... Sure there is a lot of mini related stuff there (which doesn't apply to me) but there is also a fair bit of book related stuff:

      Brain cylinder rules (that will not be a small section)
      Mythos Cat player character rules

      On top of that we get an adventure (sure it's a PDF and I'd prefer it printed, but that isn't mini related) and the free HeroLab (I don't yet use HeroLab, but I think I will now) files is bloody fantastic and not in the slightest mini related.

    17. Valentin Wake on April 1, 2016

      Too bad there is more love for the minis but I understand.

    18. Luke Murthwaite on April 1, 2016

      Now that is a bloody fantastic stretch goal!

      Whoah Sandy that's an epic super goal
