Zenwey Desert
The Zenwey Desert is labelled across the centre of Zenwey on the official world map. Several sites are marked within or beside it: Nightman Cavern, Sinking Castle and Great Jehrom.
Relation to the Artacala
In The Blood of Giants, the tribal leader Seeva names the desert past the great volcano as "the Artacala". It holds Juiyan's Castle (the map's Sinking Castle) and Nightmen City lies beneath a desert. This makes it likely that the map's Zenwey Desert is the same desert as the Artacala, but no text says so. This is left for the author to confirm.
