Khalesh was once a theocratic nation dedicated to the worship of the couatl, with a long history of crusades. During the Sundering, it was revealed that many of the noble families of Khalesh were actually shulassakar. The Inspired combined the general disdain for Khalesh with fear of these alien creatures, and the Khaleshites were largely exterminated over centuries of war. The humans inhabiting the region today are mostly descended from resettled people of the west
The Khalesh region includes a number of couatl ruins from the Age of Demons. The Inspired work to suppress knowledge of these ruins, which are hidden in wild zones and protected by the Edgewalkers.
The people of Khalesh know that demons (the shulassakar) once ruled their land. As a result, they are especially devoted to the Path of Inspiration, believing that great faith is required to resist the temptations of the altavars. They shun the ancient ruins and don't assist those who want to explore them.
