Here's an adventure for a slightly higher level party than usual. A quick trip to the elemental plane of fire is a great single session adventure, and it's pretty easy to come up with a hook to get your players there.
I tried a different technique and look for the map, inspired by the great Dyson. I wasn't pleasantly surprised with how things turned out and am going to practice this style more in the future. I would've scrapped this version and did a fresh draft, but I wanted to preserve it as evidence of my progress in cartography over time. If you'd like a bunch of free maps that look a million times better than what I do, definitely check this out.
