— Lena Duchannes explaining to Ethan Wate the powers of a Siren, Beautiful Creatures


Ridley, a Dark Siren

A Siren is a term for a female Caster that can make mortals and weaker casters do, feel or say anything they want. Because they are female and seductresses, their power of persuasion works better on men, although women can be controlled with just a little more effort.  They are a type of Dark Caster and have the power of persuasion as well as seduction. Although they aren't as strong and powerful as a Cataclyst, they shouldn't be messed with.

Their powers are extremely strong and powerful on mortals, and casters with less power. Some can control multiple people at the same time and they can also act on the emotions of people, more easily on mortals.  Depending on the Siren, they may have a "trigger" for all their powers, an object that is the starter of their magic and that makes people around them obey their commands. Ridley Duchannes' trigger is a red lollipop and whenever she wants to use her gifts she materializes one and starts sucking on it. Once under their spell, mortals, males in particular, and weaker casters are at their command and willing to do whatever it is that they want, even if it means killing themselves. Ridley, when developing her Siren powers as a young teenager, was causing boys to do whatever she wanted and become obsessed with her even as a young child. Darkborns are immune to a Siren's persuasion.


Ridley's Claiming

When Lena and Ethan were pursuing their romantic connection, Ridley had used her powers on Ethan to get him to confess secrets to Ridley that Lena had told him among other things for the sake of getting to Lena.[1] Ethan became confused as to why he had so feasibly confided in Ridley after he had done so and was barely able to withhold a piece of information from her about finding Genevieve's locket, even stating at one point how it took all of his strength not to reveal that specific detail to her.

Male Sirens

There is an outcome being relatively the equivalent of male Sirens, a Siren-Born, in a particular case where a male Caster possesses Siren-like abilities passed down from the mother's side, and the mother was a Siren herself. It hasn't been revealed if they could become Sirens on their Claiming day, or if they were identified as Sirens due to their ability, but that Casters could be born with the powers, (hence their name) if their mother is a Siren. Their existence is de facto rare, because Sirens, being Dark Casters, do not tend to marry and have children in the first place. They are more powerful then the original female sirens and their form of persuasion is normally less obvious.[citation needed] The only known Siren-Born is Lennox Gates.[2]


  • Persuasion: They are able to bend the will of a Mortals and weaker Casters very easily. Sirens can prey on men and women, but men are easier to control. Some can control multiple people at the same time. They can also control the emotions of people, more easily on mortals. Some Sirens have a "trigger" for all their powers, an object that is the starter of their magic and that makes people around them obey their commands. Sirens are unable to control more powerful or equally powerful Casters such as Evos, Naturals, and Catalysts.
  • Kelting: They are able to communicate non verbally with other Casters. Ridley Duchannes, being the only Siren mentioned in the seires, is the only Siren known to Kelt. When Lena and Ridley were young, they would Kelt with each other during the day being bullied and messed with at school.
  • Enhanced Strength
  • Seduction: They are extremely beautiful and attractive.
  • Energetic Vampirism: They are able to feed off the energy and life force of mortals and presumably lesser Casters, as seen in the film.
  • Reality Warping (only very powerful ones, usually limited compared to Natural/Cataclyst, they can always materialize their trigger if they have one)

Known Sirens


  • The mark of the Siren is familiar to all Sirens worldwide and a popular tattoo. In its most rudimentary form, the brushstrokes formed a square body with a tail. When it came down to it, that was what Sirens were— pretty songbirds with nightmares for nests. Creatures with wings that still never managed to fly free. They sabotaged themselves too often for that. Talons for nails—so sharp they could draw blood, so fast you’d never know you were bleeding.
