Quest for the Unknown, an OSR Adventure Path

Created by Todd

The Caverns of Anamosa is an adventure for characters of levels 1-3, written for Old School Essentials, Shadowdark, and Bree-YARC. It is written as the first part of an adventure path designed to take characters from levels 1-12 as an adventure path that uses the classic module B1--In Search of the Unknown as a jumping off point.

Book Two Now Funding
8 days ago – Thu, Oct 22, 2026 at 01:42:27 PM

The Kickstarter for Book Two is now live. It will take characters from levels 3-5, on a part overland hexcrawl, part dungeon-delve, as they voyage to the Forbidden Plateau in an attempt to discover what happened to the heroes of old. Also, it looks like there are still ten backers that need to complete outstanding surveys from Book One so they can get their rewards!

Thanks for all your support!

Oopsies!

So, thanks to the alertness of a backer, I realized that we have not sent out copies of the From Here to There zine with physical pledges, and after a little bit of digging I realized what the issue is. Apparently, when I generate an add-on through Backerkit with a cost of 0 it doesn't actually generate it as an item, so it didn't show up on the fulfillment spreadsheet. Sorry about that! Let me take a look at it and see what I can do.

Update
about 1 month ago – Mon, Sep 21, 2026 at 05:31:34 AM

I see someone requested an update re: this project. Here's where we are:

  • PDF codes have been distributed.
  • POD codes have been distributed.
  • Offset copies have been shipped from Mixam and should arrive at the shop this week, and we will begin shipping them out as soon as they get in.

There are still 18 backers that have not filled out their survey from Backerkit, so if you are one of those and are wondering where your stuff is, it is likely because you haven't filled out the survey.

Anyone with questions, the best and fastest way to get in touch with me is via email, at thirdkingdomgames at gmail dot com. Thanks, and have a good week!

Update #7: Credit Card Charges and PDFs
2 months ago – Sun, Aug 23, 2026 at 09:11:39 AM

Credit cards are scheduled to be charged at some point tomorrow, and when that happens I'll send out all digital files that people have selected, including the pdf for this adventure. Physical books will be mailed out all at once, likely in about four weeks.

You'll be getting a code to download this adventure from Drivethrurpg. It's going to come as a zip file with the following:

  • A low-res and normal version of the pdf.
  • PNGs of the maps used in the adventure, without labels, to give to players or use in VTTs.
  • The Worldographer files for the hexmaps in the book, in case you want to modify them yourselves.

I'm going to give the print submission about two weeks before I submit the files; lord knows I've proofed this adventure enough, but there's always something I miss that y'all catch.

Update #6
3 months ago – Tue, Aug 11, 2026 at 05:30:10 PM

Hope everyone is doing well! I am tentatively going to be releasing the pdf a little ahead of schedule, assuming all of the art comes in on time, and there are still about thirty people who haven't filled out the Backerkit surveys. My plan right now, fingers crossed, is that I'll be locking surveys and charging cards the last week in August, an pdfs will be going out at the same time. 

If you haven't gotten the survey yet send me a message (best way is via email, at thirdkingdomgames at gmail dot com) and I'll resend it to you.

The conceit of this adventure is that it is Book One of an Adventure Path, and I've already comissioned cover art and maps for Book Two, as well as setting up the prelaunch page on Kickstarter (I'll likely go live with the project at the end of September, but you can sign up now to be notified).

Thanks, and be back in touch soon!
