Yuan-ti

The Yuan-ti are an ancient race, bred by the Kror to lead their draconic armies. They rebelled against their masters and believe that they drove the Kror away from Corylak. They were severely weakened by the war, and warm-blooded creatures would come to dominate Corylak. This would embitter the Yuan-ti, who feel that they freed Corylak from the Kror and thus deserve to rule.
