Supernatural Creatures

Sirens

Lore

In Greek mythology, different sources speak of two, three or five nymphs with varying names, including Leucosia, Ligeia, and Parthenope. They were originally portrayed as hideous, bird-like women, but later, because they were often associated with the sea, they were sometimes imagined as mermaids. They sang an irresistible song that compelled sailors to come to them, wrecking their ships and killing themselves in the process.

Homer tells of how Odysseus was curious to hear the sirens sing. He ordered his companions to stuff their ears with beeswax and to tie him to a mast so that he would not be able to follow the siren song. When the sirens failed to lure Odysseus, they flung themselves into the waves and perished.

A siren can change its shape to appear human. It may seem to be either male or female, depending on how it chooses to approach a victim. It can manipulate feelings of love, whether sexual or platonic, and causes its victims to kill someone they love.

The siren's call in Supernatural is transmitted through saliva. It first charms its way through the victim's defenses by reading their mind and pretending to be the "perfect person" for the victim. It then infects them by fluid transfer. The infection leaves traces of oxytocin in the victim's blood - this is a love hormone that provokes feelings of euphoria.

A siren's true face can be seen in a mirror. The only way to kill a siren is to stab it with a bronze dagger dipped into the blood of someone it has infected. The death of a siren releases its victims from its spell.
