As promised, here are a few concept shots from Seeds of Destruction. They really helped the art staff nail the look and feel of the expansion zones.

Lore for the shots:

Kaesora is one of the largest cities in the formidable sebilisian empire built by the iksar on the continent of Kunark.  Kaesora is home to the primary library of the empire as well as the royal egg hatchery.  The city was destroyed in the war against the ring of scale that ended in a cataclysmic battle between Jaled Dar and Emperor Ganak above what is now the field of bone.
