From publisher blurb:
The Salt Basin, a vast depression devoid of water and vegetation, ranks as one of the most inhospitable places in Al-Shirkuh. And yet there is life in this blistering hot wilderness. Strange creatures immune to the need for water haunt the interior, while slaves toil under the whip to extract slabs of precious salt for sale in the great markets.

Note on the religious views of the civilized inhabitants and opportunities for trade.
A new Arcane Background - dessicator magic.
7 new locations to explore and 3 major NPCs to encounter.
