I never get these out on time.
Lairs- this would more accurately describe dungeons, but I already used the 'd' post.
I recently had a revelation about dungeon design. Now, previously pretty much every so called dungeon I've run has been a ruined underground structure, that's cool I guess, but most creatures and traps and thing were pretty much random. Its hard sometimes to come up with a reason why the various creatures living in the dungeon are even there, never mind trying to explain why they haven't killed each other.
My idea was to make living, functional dungeons, instead of always just random ruins type dungeons. My idea calls for a dungeon like Minas Morgul - the "Tower of Black Sorcery" where the Witch King dwells. Here it isn't abandoned, there are hundreds of orcs or more living in it at any time. The orcs are fairly disorganized though, and dwell only on the mid levels and guarding the battlements. the depths are home to to fearsome forgotten beasts and shadows, and in the tallest towers the Nazgul work their dark magic.
A stealthy band could slip in through a drain pipe and move carefully through the lower levels without drawing too much attention, perhaps even sneaking all the way up to the tallest towers without the alarm being sounded.
