They are three seductive vampire "sisters" who reside with Count Dracula in his castle in Transylvania, where they entice men with their beauty and charm, and then proceed to feed upon them.

He sits at a table writing in his journal and, as he begins to fall asleep, sees three women standing in the moonlight who cast no shadows.

The women proceed to seduce him and, as one of them begins to kiss his neck, he feels her sharp teeth barely scrape against his flesh.

Harker soon fears for his life, at one point thinking he sees the brides dancing in the sky outside his bedroom, which strengthens his resolve to escape.

[3] Though Harker manages to escape the castle shortly after, he is badly traumatized by the encounter and is diagnosed with brain fever.

The sisters suddenly appear at a camp consisting of Abraham Van Helsing and Jonathan's wife Mina.

At the coming of daylight, Van Helsing finds that their horses are dead, possibly having been drained of blood by the brides.

First using a blacksmith hammer, he strikes a stake into her, then proceeds to operate on her, detaching the head from the body and filling the mouth with garlic.

Literary scholar Jan B. Gordon suggests this that it may have been Stoker's intent that these two are Dracula's daughters, extending the sexuality metaphor of vampirism to incest.

[7] When the brides first discover Harker, the blonde vampire is encouraged to feed on him first, with one of the others stating, "Yours is the right to begin", signifying that she has some status over the others.

Harker describes the women as "ladies by their dress and manner", indicating that the vampires are of high lineage, further suggesting the idea that they are Dracula's family.

They are also depicted in the novel calling Mina Harker their sister after she is forced to drink Dracula's blood, afflicting her with vampirism.

[8] Mina and her best friend (and Dracula's future victim) Lucy Westenra also call each other sisters in the novel despite not having any blood relation.

Their beauty and flirtatious manner appear to be their greatest power when it comes to bewitching their victims into a trance-like state.
