Here is the first adventure in the Tendrils of Fate adventure path, At the Mines of Madness. It's written entirely by me with some maps redone by Victor (aka ThePlaneswalker) and takes place in Eberron (specifically the Shadow Marches). Unfortunately since its not an "official" adventure by WotC the production value is shit and though I did some proofreading I'm sure I missed a lot of things.
Frankly, I'd consider at best to be a heavy outline of information to use as a framework and modify to taste. Also, I don't think that I can post stat blocks for some of the monsters (even though its not commercial), so you'll have to have access to either Adventure Tools (recommended) or the Monster Manual books. Don't worry, it'll tell you which ones and for what monsters.
Finally, if you dig it and would like to see more, lemme know in the comments. This took quite awhile to cobble together, so if you really like it, donations are appreciated!
