New Spellbook Featured in SPCM for Pathfinder 2nd Edition

New Spellbook Featured in Sandy Petersen’s Cthulhu Mythos for Pathfinder 2nd Edition

Check out the Cultes des Goules, a new spellbook from Sandy Petersen’s Cthulhu Mythos for Pathfinder 2nd Edition.

Written by the Comte d’Erlette several centuries ago, this work has two main thrusts. In the first part, it discusses the structure and beliefs of cults that worship the Great Old Ones and the Outer Gods, though in a rather general way.

In the second, it is a tome of the deadliest black magic: a grimoire that contains all necessary information for performing a wide variety of rituals and magic effects. Its greatest weakness is that it has few dismissal or protective effects; rather, it focuses on loosing dangerous creatures upon an enemy and spells that harm others.

Save the Date! Startropolis 2nd Edition Coming this June

Petersen Games announces the upcoming release of Startropolis 2nd Edition this June! We have updated the art and components from our first printing, and we are excited to make available this enhanced family-friendly game!

Startropolis is a modular 3D model space station game for 2-4 players. Each turn players purchase modules and connect them to the existing 3D space station which creates revenue, allowing them to purchase more modules. The player with the most credits at the end of the game wins.

Simple Rules!

Each player buys a module in turn order. A new module is added after every purchase, so you always have a full selection.

Then, in reverse turn order, each player connects their module to the space station. Take care: where you choose to place your module will impact not only your revenue, but other players’ as well!

As modules are attached, the amount of revenue they each generate is immediately adjusted on their module card as well as the revenue tracker for all players.

­There are 7 types of modules in the core game, counting the core module, for a total of 31 pieces.


The Nova Box expansion adds SIX new types of modules! Each operates differently from the six core game module types. This expansion also comes with Advanced Modules cards to replace basic module cards, rendering each color of each module unique.

Who is Brown Jenkin anyway? Brown Jenkin appears in Lovecraft’s story Dreams in the Witch House, and it is an extremely unusual entity. It is an old fashioned type of horror – a small rat-like monster with humanoid face and paws.

More like the image of a medieval witch’s familiar than a tentacled Lovecraftian thingy! See if you can find him on the cover of this new edition of Sandy Petersen’s Cthulhu Mythos for 5e Fantasy!

Here are some of the more memorable quotes from Dreams in the Witch House describing this miniature monster:

“…the descriptions of the darting little furry object which served as her familiar were so painfully realistic despite their incredible details.”

 “That object—no larger than a good-sized rat and quaintly called by the townspeople “Brown Jenkin”—seemed to have been the fruit of a remarkable case of sympathetic herd-delusion…”

 “Witnesses said it had long hair and the shape of a rat, but that its sharp-toothed, bearded face was evilly human while its paws were like tiny human hands.”
