Underdark lore question

[Eden]

Well, I got this dark area with some towers and some water. Being dark, I think it can be placed, with a few tweaks, in the Underdark. But since I don't know which areas are needed there, nor which areas are near the one we have from lore, I am asking you which Underdark areas we need - near to the one we have - can include a tower and some water. I can obviously delete the water if it's not included by the lore. Thank you

Well Misty Lake with that city (sorry bad memory), needed TLC. It was designed for an event mainly but there are a few problems with it - the main door swings into a cliff and there is a chest trapped behind a no walk zone. A city partly embedded in the cavern walls, keeping it simple?

Can't think of anywhere but the troglodyte area minus the towers. Unless they are ancient and dilapidated.

if you look at the map of the underdark that is posted on the forum you will hopefully find a suitable adjacent slot to fit in such an area between a gap along the river?
