At +Todd Edwards /Winin's suggestion, moved my dungeon inside, built inside the largest empty cave room. Now, making an entire dungeon that fits into one room is more of a challenge than I was looking for… but I can snake a hallway into another cavern if I really need it.
Anyway, now that Newfallen is inside, I have control over lighting. There's nothing more that sets the mood for a dungeon than lighting, and not working on lighting is one of the more common beginner foundry mistakes. For instance, see my original Befallen, where I had no clue. Anything you let the foundry do FOR you, like lighting or adding room decoration, just means your quest will look just like someone else's quest.
Found some lessons about mixing static and dynamic lighting for different effects, so have been starting with that here.
Also redid the well room, put some mist coming out of the well just because, and tossed a bone golem in there to stand in for Skeleton Lrodd. In the actual version, he'll be patrolling in a loop along with some other random undead who will knock you into the well to your death.
I don't really want to get hung up on putting encounters in at this point. I'd like to get the first floor completely built out, start decorating it.
