Cavern 26

 Cavern 26

Top of a cavern or a dead end, with two passages ascending up into the network of passages and a large chamber above. There are two shafts down to the sides that dead end, and several up-shafts that curve back or out. There is a up-shaft that terminates in a dead end medium sized chamber. this cavern might be a good candidate for breakdowns? Dunno, there could also be a lot of sumps if this was flipped, and some of the the areas would maybe have mud or rubble...

Vertical height is a cool cool 541 ft of stone, and in the edit, perhaps some lush greenery...

In this edit I added a sun. Just a small one.

I bet plants that grow in the underdark are very special, very unusual, and maybe even only available in this cavern or transplanted from this cavern, as they would have to evolve here or be transported to this place and it's unique lighting conditions.

What if the sun moves?
