I'm using Adv Labyrinth Lord for the basis of the game rules, but it's compatible with any Old School game system with minor modifications

Anomalous Subsurface Environment (ASE) provides the bulk of the material, including the Land of a Thousand Towers game world: https://www.lulu.com/spotlight/PatW

The Great Old Ones of the Cthulhu Mythos exists in the LoTT and Swords of Cthulhu is a sourcebook I'm utilizing:
https://www.drivethrurpg.com/en/product/404917/swords-of-cthulhu
and Realms of Crawling Chaos
https://www.drivethrurpg.com/en/product/87813/realms-of-crawling-chaos-labyrinth-lord

Another good portion of the campaign is Operation Unfathomable and the Odious Uplands, which you can get either in two separate books:
Operation Unfathomable https://www.drivethrurpg.com/en/product/233145/operation-unfathomable
Odious Uplands https://www.drivethrurpg.com/en/product/421504/odious-uplands
or as one book, Completely Unfathomable: https://www.drivethrurpg.com/en/product/484078/completely-unfathomable-swords-wizardry-edition
They're for the Swords & Wizardry rules, easily modified for any Old School edition. Location of the Odious Uplands and Operation Unfathomable will be noted later on the campaign map.

various real-world cryptids (Bigfoot Mothman, Jersey Devil, etc.) exist in LoTT and I've been using this as a reference for some of them:

Other adventures/modules: locations will be shown on the campaign map later. Of course you can locate them anywhere you like to your own personal preferences.

Note on modules/adventures: I run a sandbox campaign, but the modules/adventures are pretty much fixed. I DO NOT pay any attention to levels of the modules/adventures. It to impart the notion that life is random and the dangers are as well. So if the party happens upon module S3 for example, and they are "low level"...they better use their wits to survive. No hand holding or scaling of the adventures.

I may add the Cha'alt campaign material, but I haven't read through it all as of yet. IT seems to fit the gonzo campaign vibe I'm going for. I just have to figure out how and where it fits.
