Latest Updates from Our Project:

Shipping and Printing Update
about 1 year ago – Sat, Feb 11, 2017 at 12:00:12 AM


Shipping date of Miniatures: We have good news!  All the miniatures sets for USA and Canada backers are on their way across the Pacific, they should be arriving at your homes in mid March! The rest of the world’s miniatures sets will be shipping out of China in early March, and should arrive at your homes in April.

Book publishing date: Many have asked this very reasonable question – when will I get the book. Part of the reason we’ve had a bit of difficulty nailing this down is the accessibility of the leather we need, and far more relevantly, the 20% additional content. The latter isn’t just tacked onto the back of the book. Rather it’s spread throughout the book. This has caused additional layout, art, writing, etc. At this point it looks like the book should be in your hands in May, with the PDF delivered in March.  

In this update we’ll begin a focus on the gnorri, one of the least known mythos races in Sandy Petersen’s Cthulhu Mythos for Pathfinder.

In this update we’ll look a little at the weapons they use.

Gnorri Special Weapons:

Gnorri weapons are almost exclusively made out of the mithral-like bones of the Dahg Gahdohl (pronounced dag gadol) which are terribly vicious and dangerous large fish. These weapons, although made from bone, do not have the ‘fragile’ characteristic. Gnorri form their ‘sacred’ martial weapons from the unusually strong bones of these large sea creatures. It is considered taboo to sell the bones to non-gnorri, however finished weapons are in rare cases traded for things of value to the gnorri that owns the weapon. Also, another interesting characteristic of these bone weapons is that even after they are made and complete, they can be worked on further to become a masterwork weapon. 

Gnorri One-handed Shortspear: This spear is about 3 feet in length with about ½ it’s length being the blade. It is balanced (weight on the end) in such a manner to be suitable as a thrown weapon. 4gp 1d6, crit: 20/x2. Range: 15’. 6 Ibs. Piercing or Slashing. When thrown, damage is only piercing.

Gnorri Two-handed Long Spear: This spear is about 6-7 feet in length with about 3 feet its length being the blade. The spear is made completely of bone. It can be a reach or non-reach weapon in the hands of a gnorri with martial proficiency or someone with the exotic weapon feat for this weapon. 60gp 1d10, crit: 18-20 x2. Range: None. 10 Ibs. Piercing or Slashing. Can be Reach or Non-Reach. Deadly.

Gnorri One-Handed Short Sword: This 2 ½  foot weapon is slightly curved with a wide blade and jagged parts that tear the flesh.  It is considered a light weapon. 30gp 1d6, crit: 18-20 x2. Range: none. 4 Ibs. Slashing or Piercing. Deadly.

Gnorri One-Handed Sword: This 4 foot weapon has a slight curve with a wide blade and jagged parts that tear the flesh. If the character has Exotic Weapon Proficiency (Gnorri Sword) or is a gnorri with proficiency in gnorri sword then it is considered a one-handed weapon. Without the appropriate feat, it is a two-handed weapon.50gp 1d8, crit: 18-20 x2. Range: none. 8 Ibs. Slashing or Piercing. Deadly.

Gnorri Three-Handed Sword: Similar to the Gnorri One-Handed Sword, this 6 foot weapon has a greater curve with a wide blade and jagged parts that tear the flesh. It is unwieldy weapon that requires three hands to effectively use it.75gp 2d8, crit: 18-20 x2. Range: none. 12 Ibs. Slashing. Deadly.

Other Weapons Used By Gnorri:

Harpoon. 5gp 1d8, crit: 20 x3. Range: 10’. 16 Ibs. Piercing. Grapple.Typically used from the water to land to capture land creatures.

Underwater heavy crossbow: 100gp 1d10, crit: 19-20 x3. Range: 120’. 8 Ibs. Piercing

Underwater light crossbow: 75gp 1d8, crit: 19-20 x3. Range: 80’. 4 Ibs. Piercing

I hope you enjoy beginning to learn about Gnorri. More to come on them next week.

An Introductory Essay and PC Races images
about 1 year ago – Sat, Feb 04, 2017 at 12:25:37 AM


A quick update this week. Wanted to show something a little different, first the 4 PC races together. This (or possibly a variant) is for the beginning of the PC Races chapter.

I'm actually a little confused why the ghoul looks so feral. Maybe they're just chaotic evil.

Sandy on Horror 

And here is something from the introduction chapter - essays from Sandy about things that may be useful for gamemasters in particular. 



Next week we might be able to show you the awesome, final cover. My poor brain likes it so much I can almost move inside my can with the force of my enthusiasm.

Insanity chapter!
about 1 year ago – Fri, Jan 27, 2017 at 10:13:50 PM

Fellow Adventurers,

We told you in a prior update that we would hold off this week on our update due to a company summit (as well as preparations for going to PAX South, where our marketing/sales team is now). However, I had to sneak this one in, because the final chapter illustrations are so close, and this rough for the chapter on Insanity came in this morning. I love it!

This is actually nothing more than a photo of the real life psychiatrist (Dr. Bruce Ballon) who is helping us write the chapter on Insanity.

The Yellow Sign Cult!

I believe the Yellow Sign edged out all others, so here is the first page of The Yellow Sign Cult in the Cult's Chapter:


PDF of the page for you:

Click Right Here! NOW! Because if you don't, you'll never see the Yellow Sign!

We are getting closer to having the final chapter illustrations complete and may show you that next week instead. The final layout being done is not too far away now!

Dreamlands Cats!
about 1 year ago – Thu, Jan 12, 2017 at 10:13:24 PM

For reasons completely opaque to me, info about Dreamlands Cats beat out all other possible sections for the book! HPL did love cats!

Without further blather, here is the second page of the section on Cats! (again, not the real page number) - 


If you can't read it well, here's a link to this page as a PDF:

Next Week

Cults seemed to be the second place, so there's a new vote to be had. Which of the following Cults do you want to see a page from? - 

Cult of Cthulhu

Cult of the Black Goat

Cult of the Crawling Chaos

Cult of the Daemon Sultan Azathoth

Cult of the Opener of the Way

Cult of the Sleeper

Cult of the Windwalker

Cult of the Yellow Sign

Other Great One Cults [this is a section that briefly covers smaller cults not big enough to warrant an entire section, such as the "Cult" of Abhoth, such as it is]
