Sirens can also charge Vault Keys using their powers. All Sirens are also capable of using Eridium to amplify their powers to a greater extent. Some shared characteristics between all known Sirens are the unique markings that appear to cover the left side of their body, the ability to pass on their powers to an heir and the ability to manifest wings. While similar in many aspects, each Siren possesses a unique power that makes them different from the rest of their brethren. Twin sister of Troy, God-Queen of the Children of the Vault Twin brother of Tyreen, God-King of the Children of the Vault Vault Hunter, Commander of the Crimson RaidersĪn ancient Siren, sealed The Destroyer within the Great VaultĮx- Dahl scientist and archaeologist, ally of the Crimson Raiders Leader of the Atlas Corporation's Crimson Lance brigade Nyriad ponders on whenever or not these powers are a blessing or a curse. When a Siren passes away they either elect a successor who they pass their powers to, or they fail to name such a successor and their powers are thrown into the universe, finding a new host of its own volition. Nyriad warns that this Seventh Siren must never be found. The final Eridian writing in Borderlands 3 ("Warning") reveals that are in fact seven Sirens in existence, overturning Handsome Jack's claim in Borderlands 2 that there were only ever six at once. When a Siren dies, they can choose to pass their powers on to a specific person, or let their powers find a total stranger. The Sirens lived side by side with the Eridians, yet neither the Eridians nor the Sirens themselves know where the Sirens came from. The Eridian writings in Borderlands 3 provide more information on the history of the Sirens as they are written by an ancient Siren named Nyriad. Overconsumption of the material will have negative side effects: Lilith shows signs of addiction to the substance while Angel eventually required a constant feed in order to maintain life function due to being fed enormous amounts over a long period of time, dying shortly after her supply was cut off.

This is also seen when Handsome Jack uses Eridium to increase Angel's powers. This is seen at several points in Borderlands 2 where Lilith used Eridium to enhance her Phasewalk ability and heal herself. Siren powers are enhanced through the use of Eridium. The Guardians made no effort to stop her, and she says it was "almost as if they wanted her to get to the Vault". While the player is working their way through the Eleseer map towards The Vault, it is revealed that Lilith had been following the player the whole time. The connection between the Sirens and the Eridians is further demonstrated in Borderlands: The Pre-Sequel!. This connection is not between Eridium and the individual Siren, as Angel mentions that Maya has no previous connection to Eridium in ECHO recordings, although she is able to eventually gain a connection through study of her powers on Athenas. Patricia Tannis suggests that, because of their relationship with Eridium, there should be a connection between Sirens, the Vaults, and the Eridians. Sirens thrive on Eridium, a mineral that forms the crust of Pandora and later became abundant on the surface after the events of Borderlands. Sirens seemingly channel their powers through the arm that possesses the tattoos, which is often seen when Maya uses her power, Phaselock (but this could be because she always holds a weapon in her right hand). They manifest when the Siren's powers first develop, appearing on one half of the body, covering them from foot to scalp though some Sirens such as Amara and Steele showed having tattoos on the other side of their body (Steele had some on her belly and Amara gains more and more tattoos on her back and right arm as she gets stronger). The unique tattoos are both a defining feature and a side-effect of being a Siren. However, exceptions to the "women only" rule do exist, as shown by Troy Calypso, who manifested similar but weaker powers due to being a parasitic twin to Tyreen Calypso. Sirens are typically female, and will develop powers whenever they inherit them from the previous Siren. There are reportedly six Sirens in existence at the time that the events in Borderlands take place.
