I would go for circular towers, as GW did for their elven fortress, tapering slightly towards the top.
All the descriptions say that they appear to 'grow from the living rock itself', so a base of some sort would probably look good, rather than just being placed onto the table directly.
As to how you would get a circular tapered tower...
I honestly have no (good) ideas.
