- "It's so easy for you to ask for our help, it cost you nothing. You get to live forever while we will die. We are going to die and it won't be for you"
- — Madeline
Madeleine Van Tassel is a sibling of the current line of Van Tassel children. She has three other siblings, Colin, Ophelia and Luna.
The Van Tassel siblings are witches who descend from the Van Tassel line of witches. They are the descendants of the witch who gave her blood to turn the Darling family into the first vampires. Each sibling has one specific power inherited from their ancestor, Katrina Van Tassel.
Madeline and her family were made aware of her Wiccan background at a young age and were schooled in the art. Both parents came from a Wiccan background, many witches think it important to marry another of their kind to keep the bloodline pure.
