Clogwyn Prison was once a dwarven prison in the Black Loch. It used to be above the water, but a giant hole opened in the roof of the loch and the surface sea above started pouring water in. This hole was called the Great Breach and the rise in sea level it caused put quite a few places underwater.
This was inconvenient for some, but less so for others. For the coven of sea hags that moved into Clogwyn Prison afterwards, it was pretty fantastic. And you have to imagine that the kuo-toa were, at worst, fine with it.
I think Clogwyn would be a pretty interesting place to pass by on a ship. It's the kind of thing you might not need to hook a party into exploring, since they're probably going to be pretty curious about why the roof of a building is sticking up out of the water. Just make sure they found a few potions of water breathing on their last adventure if they're going to need them.
There are only two locations left to draw in the Black Loch: the duergar outpost and the fortress ruins. I'm going to draw the duergar outpost next, but before I draw the last map, I want to get everything else done first. Because there are a few other things to do to finish the Black Loch and, when I draw the last map, I want that to be the last thing left.
So I'm going to take care of the other stuff first. This includes:
All of these are small tasks. A day or two each, at most. I think I can get all of it done, along with the last two maps, before the end of next month. Then I've got a new spelljammer to draw, as well as an Indian temple. And, of course, with the Black Loch done, we'll need to talk about the next big project. I'll fill you in on the plan and you can let me know if you think it's worth spending the next few years drawing.
Well, I think that's it. If you've got any thoughts on any of that, let me know!
