All dyheli possess Mindspeech as a general rule, and are strong enough to take control of others and force their bodies into doing something without the individual's consent being a necessity, but they only do this when it benefits the herd, and do not typically do so to humans unless the human has been adopted into the herd as an official member of the herd. (Or, if they're part of a group traveling together, in which case they will consider the group and everyone in it no matter species, to be their herd, and will vigorously protect every member of the herd as well as they can.) Ethics involving the dyheli have become a topic of much internal debate for many who have had to take advantage of this particular ability. (Owlsight, Owlknight)
