Chuuls are surprisingly intelligent, leading many to speculate fruitlessly on their origins and motivations. They speak a chittering, burbling dialect of Common, but few are inclined to speak to those outside their race, and if chuul society exists beyond their frenzied mating season, humanoids have yet to record it. Instead, chuul intellects seem entirely devoted to seeking out the perfect ambush sites to attack other intelligent creatures and decorating their elaborate lairs with trophies from their kills. Though the chuuls themselves seem uninterested in using tools of any kind, they have an almost compulsive need to collect keepsakes from their victims.
