And if you don't feel like trekking over to the website, I'll just leave Eleanor's mini bio here:
Age: 24 Forever
Eyes: Brown | Changes Color With Mood
Title(s): Titulari Secreta in Vampire Order | Self-Proclaimed "Queen" of Elite Creatures
Eleanor L. Black is known by now throughout the fanbase as the antagonist of the century. Driven by a rather unsettling power, Eleanor has only one thing in mind: acquiring Xavier Delacroix as her King. And the power she's gained? That's for the betterment of the entire Dark World, of course.
After all, learning Dracula's incredibly dark secrets does something to a mind. What has it done to Eleanor? Well, it's made her just a bit more unhinged. She would call it 'freedom.'
The Vampire that was Eleanor Black was an obedient student (to a fault) and never stopped questioning what more remained in the Dark World; what made she and the other Creatures what they were. Of course, her mentor never took this in kind but Eleanor hardly cared. Once just the slightest glimpse of secrecy was shown to her from her mentor, she took it upon herself to learn all she could that Dracula kept secret.
And she did. The rest is history.
