The Temple City of Tlax

Description
The Temple City of Tlax is the capital of the Saa'ur, the dominant people of the Sllithàna Swamplands. It is the largest city in the region and is rumored to be unimaginably wealthy, more so than even Onkh-Morpark. It is rumored that its grand pyramid temples are made of gold and it streets are studded with precious gems. Whether that is true is doubtful, but there is no real certain way of telling, since no reliable accounts of Tlax are known; the cruel Slaadi overlords of the Saa'ur see to that.

However, judging by other, more well-known Saa'ur cities, Tlax is most likely partially or even wholly submerged under swampy waters. Only the taller structures, like the staired pyramid temples and palaces, would rise out of the water. Most of the other buildings are underwater, connected to the surface by a set of reed pipes that ventilate the air pockets within.
