That’s fantastic, thanks for sharing.
For things I’ve written, Wallet Dungeons is the only thing that creates full places to explore. I’ve also got Waypoints but that’s more of a feature within a larger map.
From other people, there are some online ones I’m aware of:
Some pen and paper dice rolling:
Hedonic Ink’s Die Drop Dungeons
Esoteric Enterprises has a bunch of die drop generators in it, but it’s all modern/urban fantasy stuff and may not be the genre or tone you’re looking for.
I’m sure there are more that I’m not thinking of at the moment.
