Ollin’s Borehole – An Abandoned Deep Gnome Mining Outpost

Ollin’s Borehole is a sapphire mine in the Black Loch. Well, it was a sapphire mine until some duergar bandits found the place, smashed their way in and killed everyone. Since then, it’s just been another hole in the ground. But, as holes in the ground go, I think this one is pretty interesting.

I wrote… let’s call it “the framework of an adventure” for this map. I’m hesitant to call it an adventure because there are a few things missing from it, most notably the monsters. I left them out because I wanted to make it flexible for parties of any level. So, if your players are level 2, this place is full of kobolds. If they’re level 10, it’s full of umber hulks. You get the idea. I also don’t specify the amount of loot to be found, largely for the same reason. Basically, I left out the stuff that I’d typically change when running an adventure that was made for parties of a different level than mine is.

Anyway, it’s called “The Lost Sapphires” and it’s in the DM notes. I’m curious what you all think of it, so I’m giving it away to everyone. It’s nothing complicated, just a single-session dungeon run, but it’s an easy way to get your party into Ollin’s Borehole. I can’t promise you’ll love it, but I can promise it will explain why there’s a big pile of beds at the bottom of the pit.

And I can promise that you will have a 15-minute argument about how much those beds should mitigate falling damage if your party’s rules lawyer lands on them. I apologize for that in advance.

I’ve got an unfurnished version of this map on the way, which I’ll have for you tomorrow. After that, I’ll be drawing the Cobalt Flotilla,  a floating community made up of a bunch of ships lashed together, forming a big, wooden island. And then I’ll be drawing a historical map, the Château de Chenonceau. It’s one of those places that’s straight out of a fantasy map, except people actually built the thing in real life. As inspiring as I found it, it seems like the least I could do is draw a map of the place so it can have a few more battles.

There’s an annotated version of this map available to patrons.

  1. Your map is beautiful. I used it in my first DM one shot in 20+ years. I had it being looted by Duegar.

    My PC’s walked into the borehole amazed by your map. They rushed to the bottom. I included your “bag of sapphires” but they ignored the three clues.

    Thank you for your skill

    1. Glad it went well! Sorry they didn’t find the loot, but, to be fair, the duergar didn’t check the mattresses either.
