It's incredible that we are less than a week into the campaign and we have officially crossed $50,000, unlocking the American Wilds Setting Primer for all backers!

This PDF supplement will expand on the world of P.T. LaMarck’s Cryptid Codex, introducing new regions, story hooks, and encounter ideas to help GMs build full cryptid-themed adventures. It is all about bringing the folklore to life and giving you tools to weave these creatures into your campaigns.

Because of your support, every backer at the book tier or higher is now getting a ton of extra content completely free.

You’ve already unlocked:

  • New Player Backgrounds including cryptid hunters, folklore researchers, and investigators.
  • Artifacts of the Unknown, a collection of rare and powerful magic items tied to the creatures of the Codex.
  • And now, the American Wilds Setting Primer, a guide filled with world building information, encounters ideas, and story hooks.

We’re so thankful for how much energy everyone has brought to this project. The comments, shares, and support have been incredible!

Up Next: Versatile Lairs

Our next stretch goal is Versatile Lairs, a new collection of modular encounter locations designed to pair with any cryptid in the Codex.

These lairs draw inspiration from the American wilderness, from the misty Pine Barrens to the deep Northwest forests and the endless underground caverns beneath them. Each one includes unique hazards, narrative hooks, and scalable challenges to make your encounters even more memorable.

With your help, we can bring these dangerous locations to life and give every creature a place to call home.

Thanks again and have a great weekend! Next week we plan to have some more art previews ready for you!!

Artifacts of the Unknown Unlocked!
5 months ago – Thu, Oct 23, 2025 at 05:43:01 PM

What a start. In just three days, P.T. Lamark's Cryptid Codex has already grown beyond what we hoped for. More than 650 backers have joined the expedition, rocketing us past $37,500 and keeping the campaign on track for an incredible month ahead.

From day one, you’ve turned this project into a community. Seeing your excitement in the comments, the state cryptid guesses, and all the shares across social media has been awesome. Thank you for helping this project reach even more cryptid hunters!

Goal Unlocked: Artifacts of the Unknown

We’ve reached over $37,500, unlocking Artifacts of the Unknown. This goal introduces a collection of magical relics drawn from cryptid legends, each with its own story and mystery. Every artifact ties back to a real piece of folklore, designed to weave cryptid myth into your world. 

These powerful magic items make a great major quest item for one-shots or campaigns.

Up Next: American Wilds Setting Primer

Our next goal is already closing in! At $50,000 we will unlock the American Wilds Setting Primer, a digital guide for all backers.

This PDF expands the world around P.T. Lamark’s Cryptid Codex, offering towns, regions, and encounters designed for running your own cryptid-themed adventures. It’s a way to turn the book’s legends into a living, playable setting. And it becomes a FREE download to all backers once we hit 50k.

The Adventure Continues

If you haven’t already, come hang out with us on Discord. We’ve set up a dedicated Cryptid Codex channel where backers are sharing favorite creatures, encounter ideas, and theories about what P.T. Lamark might have found next. 

Now, we’re heading into the weekend with new stretch goals ahead and fresh art to share. Thank you again for making this launch such a success!
