Dungeon 23 Week 4 - The Glistermarsh

Welcome back to my Dungeon23 challenge, where I'm making a megadungeon for the Dungeon Crawl Classics RPG, one five-room dungeon at a time. Last week, we introduced where the water that sustains this part of the dungeon comes from, so this week, we're pivoting to what happens when that water meets the underground and alien environments of the Old Priory dungeon halls: a big, bioluminescent marsh!

As I think I've alluded to in the past, when I'm designing this dungeon, I have a sort of "main story" in mind for each section. In this part of the dungeon, it's the conflict between the Lost (the inhabitants of Nowhere Market, detailed in Week 2) and Fune's Basalt Tower (which will come up in weeks 10-13). This wetlands section (the Mistfall last week, and the next few weeks centered around different things that happen when a bunch of water gets dumped in a dungeon) is more "side quest" or verisimilitude in intent, but that doesn't mean I can't slip a few main story things into it:

The first of these, of course, is the Basalt Amalgam at the end of the adventure. This gives a bit of a foreshadowing that Fune can reach pretty close to home for the Lost and summon chaos, so the party probably shouldn't sleep on dealing with them. Plus, fighting a crumbling basalt elemental in a glowing cattail marsh can give a pretty memorable encounter to cap of this bit of exploration.

The second is what might happen right after dealing with the Amalgam - the discovery of Myrmakrii at the bottom of a small pond. As I'm fleshing out my list of secrets, I'm making sure to put the notion that the Basalt creatures are drawn to magic, and a few other clues that there might be a magic weapon somewhere in the marsh, so that the party has a reason to hunt around for something good. Aside from a powerful demon-slaying sword, Myrmakrii is a hint at the second "main story" thread running through this place: following in the footsteps of a long-lost "Tonal Expedition." What this is will be fleshed out in the deeper parts of the dungeon (or, you know, from half paying attention to Elder Scrolls lore...), but I wanted to start hinting at it now so that it comes out as a logical discovery rather than a weird intrusion later on.

Dungeon 23 Week 9 - Cliffbarrows

Welcome back to another week of Dungeon 23! This week is the first entry in a brand-new region of the dungeon, a sublevel of level 1 dominated by Fune and the Basalt Warriors. Last week we looked at Deepcrossing, the fortress Fune has for safeguarding the only entrance into this area. This week, we look at the cliffbarrows, the first stop on the long switchback leading down to the basalt flats below. More than anything we've seen so far, my goal for this place is to signal to the party that they are somewhere different now. They travel through the long corridors of the Deepcrossing, feel themselves descending into the earth, and suddenly come to this wide open basalt space. As they descend the ramps to the flats below (which will be more detailed next week), they are immediately set upon by boulders thrown from the cliffs above! Here, hidden in the cliffs, are horrible mixtures of human and basalt, failed experiments from Fune's prisons. They are hostile, and survive by taking...

Dungeon23 Challenge - Beginning

Like everyone in the online TTRPG space right now, I'm embarking on the #Dungeon23 challenge. As originally proposed by Sean McCoy , the challenge says to create a megadungeon by plotting one room a day for a whole year, ending with a 365-room monstrosity to inflict on your hapless players. While Sean's advice is to focus on making one room per day without worrying too much about a grand plan, I had some quiet time over the holidays and can't stop the grand plans from coming even if I wanted to. Rather than fight myself, I'm going into this with a bit of a roadmap sketched out: First, as soon as I saw the Dungeon23 challenge, my mind went to "make one 5-room dungeon per week." I rely heavily on the 5-room dungeon format for my drop-in store games - they're a reliable way to get a satisfying adventure crammed into a 3-hour session with people who may or may not have played together before. In brief, the 5-room dungeon format says to make a dungeon with fi...

Dungeon 23 week 3 - Mistfall

Welcome back to week 3 of the Dungeon23 challenge. This week, we have a look at the area to the north of the False Priory, where we answer the question "wait there's a whole town living in this dungeon? Where do they get their water?" From a giant, mysterious waterfall of course! When I first thought up this level of the dungeon, I knew that I wanted to have a fair bit of it be marshy, fungus-filled terrain (for aesthetics), and that I wanted part of it to center around a mysterious ancient magi-tech mill (see Week 6, when we get there). Both of these would require a source of running water somewhere in the dungeon to permeate a bunch of the place, so I decided early on that there would need to be a waterfall somewhere in there. What we have here is a pretty standard water-dungeon set of encounters, for two reasons. The first is purely practical - that this week has been pretty rough for non-RPG reasons, so I didn't have as much time to dedicate to this project as I...
