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.

Latest Updates from Our Project:

Update #7: Credit Card Charges and PDFs
22 days 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
about 1 month 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!

Update #5
about 2 months ago – Fri, Jul 17, 2026 at 08:18:03 AM

Just wanted to give y'all a brief update. We're still on schedule; art is underway, and I hope to have finished pieces by the middle of August. I'm going to be sending out Backerkit surveys in about two weeks, at the beginning of August, and will plan on charging cards at the end of August. PDFs should go out in the beginning of September, and then I'll place the order for the physical books, which should arrive by the end of September for distribution. I'll be sure to let everyone know if anything changes.

Update #4

Just wanted to give everyone an update that we're still on track for fulfillment of this project. I'm waiting on two more finalized maps from the cartographer, and am polishing the document to be sent to editing. I should begin commissioning art for the project in about a month or so.

Update #3

It looks like a couple of people have requested updates. Everything's moving along; I'm working with the cartographer to revise the dungeon maps, keeping the general themes and important chambers, but streamlining them. We're still on schedule.
