Their combined aspects of humanoid and serpent accurately model their natural inclination to switch between kindness and cruelty. \n'b' Yilankas prefer to live far from the constraints of civilization. They make their lairs in small cave complexes, and they favor areas with strong winds where the action of the wind passing through the tunnels creates an eerie sound that keeps predators away. Yilankas enjoy isolation and are loath to entertain a guest for too long. They find other creatures tiresome and often use violence to drive off visitors who have overstayed their welcomes. Nomadic people of the desert speak of how the blood and bile of yilankas can cure any ailment. The hunting of yilankas for their humors in ancient times led to their near extinction and current distrust of humanoids. Creatures that approach a yilanka carefully and respectfully find that they have a keen knowledge of medicine and natural remedies. If their knowledge is insufficient to cure a petitioner\xe2\x80\x99s ailment, a yilanka may be convinced to trade its blood if an acceptable offer is made.'
