I have begun working on a mod, redesigning the Redoran stronghold at Bal Isra, and its surroundings. I would like it to be as lore friendly as possible, but can't find anymore information except that it is named after the rows of stones.

Quote from The Imperial Library:

Bal Isra ('rows of stones')

A place on the road from Ald'ruhn to Maar Gan, named after the rows of stones there.

If there is more I should know, or any ideas that seem appropriate for the location, please feel free to post.

There isn't much else on it aside from it being a curious natural feature.
