When I'm out of ideas about how to make my dungeon interesting, I put down the Dungeon Alphabet from my shelf, which is probably the best goddamn sourcebook written about dungeons. Another thing I usually do to make dungeons more interesting is taking examples from the genial Paul/Jennel Jaquays and include a lot of loops and forks in my dungeons. I hate linear dungeons, they are boring to explore.
OMG.
The Dungeon Alphabet! I agree, it is the most amazing little source book that I've
never used it. I had planned a whole mini campaign around it but it never happened. These are excerpts from my blog notes..
So, starting at letter A on the first level of the dungeon, the party randomly encounters an ALTAR...
...(d20)...Bright scarlet with inlaid veins of silver. A humanoid head (a decapitated mind flayer) its atop the altar. Engraved on the stone floor in front of the altar is a pulsing red unholy symbol.
On the west wall is a door leading to Area A2. But just then, there is a sudden clamor in that tunnel and the heroes see...
The PCs themselves but older and better equipped than they currently are. These other PCs are the party’s older counterparts who traveled back through time to warn the party of a catastrophe about to befall them in the dungeon. Disturbingly, not all the PCs are present in this other party. The missing members died in the event about to take place. Should the heroes heed their older selves’ warning, the catastrophe fails to occur, but this means they have no reason to later come back and warn themselves of it, making this meeting impossible. Referees with a fondness for temporal paradoxes will undoubtedly find ways to drive the players crazy with this encounter.
Holy poo, the roleplaying potential in the first TWO ROOMS of this adventure is amazing!!! And if you play it by ear, you can weave a thread through the letters as you descend toward the infamous ZOWIE at the end, maybe the thing that the party was sent back in time to warn their younger counterparts about! Or not. Who knows.
I got to see what happens next. Maybe the party recruits their older selves. Maybe the future heroes run and flee, but not before telling the halfing DON'T look in the hole, something nasty nasty will happen to you.
So they continue, somewhat shaken now, and reach B...a room of meticulously ordered and arranged books with 100 titles (see list) and strange properties. B2 is also here shortly after, Battles, as an unexpected opposition reaches the same room of books, and....(d20)....
The party’s opponents are revealed to be entirely different creatures than the PCs believed them to be. The fearsome orcs are actually bandits wearing costumes as part of their criminal scheming; the skeletons are all living humanoids that drank from a pool which turned their skin and organs invisible; or a giant lizard is truly a dragon that lost its wings to an enchanted blade.
You would need a box of minis, a grid map, and dry erase colored markers and just make up stuffas you go. Fun. Gonzo adventure. And you could start at A and roll again and have a whole different game.
It is known as the Dungeon of Dreams, The Mountain of Ill Repute, and the Fortress of Insanity, among others. Here, reality is warped and bent as multiple planes of existence converge on one spot deep beneath the surface, the results of a mad lich's experiment gone horribly wrong in ages past. Over time the rooms and hallways can fade and change and slide from existence, only to be replaced by something completely different. Many have braved the unhallowed depths; few have returned, and most that do return are the ravaged souls of the departed, lamenting their eternal damnation and cursing their foolishness. But for those who can survive to the lowest bowels of the Dungeon of Dreams, indescribable riches await...could that be YOU?
Note that this type of storytelling gameplay requires a DM quick on his feet who can try to tie inherently nonsensical events into a semi-understandable whole. Giving them a goal to get to the Z-Zowie is the crazy part, and it might just be a kitten.
