I can see maybe the dank crypt and maybe the druid grove, but the owlbear cave, the spider lair, the necromancer's lair, the hag lair, the goblin base basement, and THE UNDERDARK. It's dark, yes, without rays of sunlight, but my goodness every inch is lit.
/especially/ the spider lair! There's a village on top of it! There are no holes in the roof or we'd see them in the village
