Stuck on ramparts?

[Viper]

I can't seem to find the exit to the ramparts. I know it has to be there somewhere, but I just can't find it. Note: There are a couple areas I can't access because I don't have the runes. Any help is appreciated. :)

Teleport back to the first teleporter all the way to the left on the surface and climb down that tunnel.
Somewhere in those rooms there should be a small hole in the walls on the right side that lets you roll through it to access the rooms on the right that are now partially blacked out in your picture.

Holy cow, I didn't know I could roll under those. Thank you!
