Banshee (Roswell Conspiracies)

The Banshees are a race of humanoids with supernatural abilities that came to Earth and settled on Ireland in the year 527 BC.

Anatomy
Banshees are physically similar to Humans, thought only females have been confirmed to exist. There are many Banshees who have hair colors such as pink, purple, green and white.

Lifespan
Banshees have long extensive lifespan that are hundreds or maybe thousands of years long. Their collective life force is bound to the Tree of Light, a magical tree from their home realm. Every individual Banshee is physically represented by some sort of glowing 'light fruit' in humanoid form. If the Banshee dies, the glowing body-shaped fruit will dissolve.

Reproduction
Banshees are known to be capable of progeny to extent, with Sh'rian being the daughter of Queen Mab. However, it is unknown exactly how this is accomplished. It is possible this may be due to some sort of mystical parthenogenesis.

Powers and abilities
Banshees possess a variety of powers such as teleportation, energy blasts, flight, and a form of clairvoyance in which they predict when someone will die, which led to the Irish legend about them.

Their most well-known ability is producing piercing shrieks.

In group flight, they can form a camouflaged single entity, some sort of amoeboid energy bubble.

Banshees have telepathic abilities to go into someone's mind. However, this would make the user and the subject bonded for life, even share their lifespan.

To be capable of travelling through space, a Banshee can merge into a single gestalt-form of a 'ship' made up of energy.

Weaknesses
A Banshee's biggest enemy is technology and electricity, which they defy and combat ferociously since they regard technology as a nature destroying abomination.

A Banshee who is isolated from the biosphere or nature will sooner or later fall into a frenzy, where she merges with technology into a bionic cyborg-like being and thus tries to turn all artificial materials into organic matter and eventually dies the so-called iron death. Only magical Earth stones (rune stone marked with the rune Fehu) from the Banshee realm can prevent the iron death.

Vampires are another big threat to the Banshees since they are very technological-ridden beings and even capture Banshees alive to use them as power sources until they die. The Vampires even manage to get access to the mystical Banshee realm which usually is physically impenetrable for other beings as to sap the Tree of Life, trying to drain the collective Banshee life essence, as to get rid of the Banshees once and for all.

A Banshee who gets bitten by a Vampire turns both into Banshee-Vampire hybrid, empowering the Vampire and putting the Banshee under its spell.

History
Centuries ago, the Banshees fought a major battle against the alien race of the Minotauri and magically captured two of them (Kahn Mort and Charon) together with a mechanoid parahound called Cerberus in a stasis chamber.

The Banshees once lived in harmony with the Humans until they were poisoned by their dependence on electricity. They have been at a constant warfare with the Vampires in attempt to use them as biological batteries or capacitors for their teleportation machines.

Culture and society
The Humans are regarded as outworlders who are infected with technology as well, that's why Banshees usually shun and disrespect people from Earth.

Other races like the Aesiri (Loki and Odin) are connected to the Banshees as well: they were once created to protect the Earth from a coming invasion by the Shadoen, an evil alien race that tries to infiltrate and conquer humanity.
