In the late 20th century, the Gemini Coven was plagued by the birth of another siphoner, Malachai Parker, the son of Coven leader Joshua Parker and the twin brother of Josette Parker, who had been born a regular witch. Eventually, Lily and Julian turned the remaining siphoners, seeing Valerie's potential upon realizing that she had retained her ability to practice witchcraft and was now able to draw on her own vampirism as a source of power. When Julian learned that Valerie intended to leave their family to start a new family with Stefan, he beat her so severely at the harbor that she miscarried and fell unconscious, allowing Julian to bring her back to Lily and lie to her about what happened, claiming instead that Valerie was mugged and beaten, since he knew that Valerie could not expose him without revealing her relationship with Lily's son.Дistraught as a result of Julian's monstrous acts and her miscarriage, Valerie killed herself by overdosing on laudanum and drowning in the bath, but because Lily had healed her with vampire blood earlier, she awoke in transition and became a vampire with witch power the first of her kind. Shortly afterward, their trio grew larger after a fellow exiled Gemini siphoner, Oscar, joined them.ДЄfter Valerie was sent to check in on Lily's human son, Stefan Salvatore, in Mystic Falls, she ultimately fell in love and had sex with him, resulting in an inadvertent pregnancy. While Lily was learning control over her vampirism, she took Valerie under her wing, forming a trio with herself and lover, Julian. One of the siphoners, Valerie Tulle, became a nurse at a sanatorium near Mystic Falls, where she befriended one of her patients, Lillian Salvatore, who ultimately died with vampire blood in her system and became a vampire herself.

While on the way to destroy the Gemini Coven, they were imprisoned in a prison world by them. As vampires, they discovered that they could siphon the magic holding them alive, becoming witch-vampire hybrids. These six individuals, eventually calling themselves Heretics, were befriended by Lillian Salvatore in the late 1800s and she turned them into vampires. Over a course of over a decade in the mid-1800s, a number of siphoners were exiled from the Gemini Coven because of the witches belief that they are abominations. During the final stages of birth, a surge in siphoning may be observed which may put said mother in danger.

It was revealed that siphoners begin to siphon magic from inside their mother's uterus, starting with feeding on very small, almost imperceptible amounts of magic at a time that will grow larger and larger as the pregnancy continues.

In This Woman's Work, the birth of twin siphoners, Lizzie and Josie Saltzman, was shown for the first time. In the case of twins, there seem to be no indication that they both must be either siphoners or regular witches, as evidenced by the existence of three sets of twins from the Gemini Coven-the twins Olivia and Lucas Parker were both born as regular witches, whereas their older twin siblings Josette and Malachai Parker were born a regular witch and a siphoner, respectively, and the twins Lizzie and Josie Saltzman were both born siphoners. Their conception and birth appear to be the same as that of ordinary witches, given that many siphoners do not know of their true nature until adolescence. Very little is known about siphoners, especially with regards to how or why they came into existence.
