Sirens are the silver-tongued interrogators and diplomats. Highly deceptive and charming, their voices are said to be pleasantly hypnotic. Sirens have been trained to read people's body language and read lips. They often know more than one language and are trained in the art of social manipulation. Though their augmentations allow for them to hypnotize people and put them into a highly suggestive state, most Sirens don't use it as a first resort, putting their training to good use.
Though this hypnotic state is hard to resist, it is not infallible, which is why the Siren will rely on their other skills in tandem with their augs. They are master manipulators who have been taught to read people and how to play them.
Do NOT listen to them.
