A We Are The Devil's Daughters Trilogy (Zahara, Madrina & Euphamia; unedited)

It was hard enough being a female in The Null, the deepest darkest prison in all of The Void, but when you add in the fact that your father was the 'Devil', and your mother was...
How was one young female supposed to be herself, let alone three of them?
Madrina was the oldest of the three, born a whole two minutes before her sisters, she was more like her mother than the others. She valued the strict rules of her people, her never ending loyalty to her duty making her the perfect Warden for The Null, charged with keeping order in her father's most sinister prison.
Zahara was the middle sister, the perfect balance of her mother and father. She had learned to bend the rules when needed, and she could navigate the fine line between right and wrong and slip into the shadows of ones mind. Her position as The Null's Head Transporter reflected as much, it was not easy collecting the dead, especially when their destination was the depths of Hell, but Zahara got the job done.
Euphamia was the youngest of the Devil's triplets and was the spitting image of her father. She knew there was a reason for the rules, they helped keep order a midst the chaos, but that did not mean she had to like them. Her dark nature kept her in the shadows, suspicious of everyone and everything. This, and her ability to see the darkness in others, made her the perfect Hunter, tracking down those who would dare to escape her father's domain.
Three hundred years old and destined for great things, the daughters of Lord Eroch know that war is on the Horizon and that an enemy of the past threatens to destroy everything in its path; and they cannot fight it alone. Each must face a challenge, and each must succeed in hopes that they will rid the universe of the horrifying scourge of the Eno'tai.
