With the word “dungeons” as a part of literally the name of the game, it’s surprising how easily these can be forgotten. I know that, for me, if my players are going to have to explore one, it needs to matter.

It’s day twelve of 30 Days of D&D, and the topic is Favorite Dungeon Type or Location.

Video games like Skyrim are awesome for the quality of the sandbox the player is placed in. I remember hearing that as soon as you finished the tutorial / intro, you faced an unstated choice:  Follow the road to the next storyline quest location, or wander in whatever direction you liked, exploring the region and its assorted scenic points.

D&D can be like that. Some DMs prepare that way, sprinkling the setting with a whole lot of everything else that’s going on in the world. I think that’s a good component of a game, especially if you’re trying to maintain a sandbox style or at least feel.

At my best, I keep a few of those parts of the world at the ready in a computer file or hard copy folder, just in case the players decide their current plan isn’t as interesting as some bit of news or rumor they hear, or some random clue they find in the wild.

On the one hand, I don’t want them to feel like they’re on rails in any way–“You can only go east because, um… reasons.” Namely, because that’s where the thing I prepared is on the map. (I did have to admit that to a group of players once. Didn’t like it.)

That said, I also don’t mind if they end up mysteriously coming across the orc cave I’ve prepared, regardless of whether they turned north toward the mountains or east into the forest. It feels natural and unexpected, because I haven’t tied myself down to “this dungeon exists at this partiuclar spot, period dot, end of story.”

Even more than location, what matters to me about dungeons is purpose. Every dungeon or mini-dungeon I build is meant to have some kind of meaningful end result.

Maybe it’s finding out more information about a bigger threat to the region or discovering an item necessary for the Big Bad’s ultimate evil plan.

Maybe it’s a plot twist or even a low-scale moral conundrum. Those goblins you thought were a threat? They’re actually in trouble, oppressed by the kobolds who moved in with the young dragon they serve, or deceived by their newfound friend, the hag. This sort of thing has led to some great role-playing and even a few recurring NPCs of an unusual variety.

Maybe it’s just some object of great power, the knowledge and details of which have been lost to time. I don’t know why, but I always love the “ruins of the ancient, more advanced civilization” background to a dungeon, with objects that exude strange powers, interact with the players in various ways (usually bad), or reveal secrets about the world on a much larger scale.

I care far less about the location or type than about why it matters for these heroes to stomp through this particular network of tunnels and caverns.
