"Markarth Side is entirely within a stone wall with no buildings whatsoever poking out of the surface."
No buildings poking out? within a stone wall? What?
Whoops, misread it - here's what it actually says:
"Every big settlement is unique. The city of Markarth Side, for example, is set into dramatic stone cliffs, with buildings teetering on the end of sheer drops"
Apologies for that, I was reading through it as quick as I could to get it on here and must have missed the bit on the end about the sheer drops D
