Outside the city, there is a small U-shaped mountain range comprising the mostly buried jawbone, and teeth of a long dead titanic creature. The ivory of these teeth is a popular building material for those wealthy enough to afford it. This ivory is also used for colossal statuary, which is currently much in vogue.
The mountain quarries compete fiercely to deliver the largest blocks, which often measure many meters to a side. Exceptionally massive blocks fetch astounding prices and the caravans which transport them to the city are frequently raided by profiteers and rivals.
