Back during version 3.0, FFG made 24 different mini-adventures for D&D, all set in the world of Mennara.

Here's a link for them: https://www.rpg-resource.org.uk/index.php?article=1000&visual=9

They have all kinds of lore I haven't seen before.

Nice find 😀

Here's the actual adventures. The last 7 though, are just generic in setting. http://home.miesman.nl/files/Adventures/

I've already pulled a lot of lore from them (and only through about the first 5 or 6 of 17 so far)... Things I pulled from it (monsters, places, NPCs, gods, items, etc.) can be found here in this folder:

It will be a growing collection as I go through all of them. The one I'm doing now (The Dark Tribe) even has a complete small town with town map, NPCs, and businesses. https://www.scabard.com/pbs/campaign/235523/place/405355

Though I'm still fleshing out the businesses a bit, so they'll eventually be pins on the town map.

This is awesome work you have done here!

Thanks! Enjoy them!
