I drew Owen’s Mine sometime around June of 2011.
Wait… 2011? I’ve been blogging here for a while, eh?
Anyways, yeah, Owen’s Mine. It was inspired by a game of How to Host a Dungeon that I played where the kobolds had their base of operations just beside the human mines, without any actual connection between the two.
What’s exceptionally cool is that Vance Atkins then used the map to write up a set-piece encounter / adventure. Then another, and another, and one more!
So over on his blog (Leicester’s Ramble) you can read up on and download all four variations on Owen’s Mine, each with a different concept – at least one of which will probably mesh with what’s going on in your game. 🙂
