So, I've decided to start a Patreon, producing mini adventures to be dropped into sandbox style campaigns.
My Low Fantasy Gaming RPG is in the wild as a free PDF, so naturally my adventures use the LFG ruleset. Of course it's easy to convert them to any d20 system (or similar).
Alas, illustrations are not free, so I'm charging $1 for each adventure.
I've called them "Adventure Frameworks", because they aren't fully fleshed out adventures - they're "adventure skeletons" - designed to be dropped into a fantasy location along with a rumour/hook, to help the GM run a sandbox style campaign with confidence. They run about 4-6 pages (excluding credits), book marked PDF only.
There's a free example at the link above: the Tomb of Horutep. Enjoy!
