Creatures of Darkness

After a worldwide Cleansing of "Unholy beings", those being species such as werewolves, vampires, witches etc, everywhere seems free of them, most of them driven into extinction.

But is that true?

Small bands of them have remained hidden, underground or in abandoned buildings, trying to keep themselves safe and hidden. Yet humanity is weeding them out and killing them off.

23 year old Selyna Komorov is from the werewolf pack in Moscow. After witnessing the murder of her brother, she sets off to protect her remaining pack members from the humans.

20 year old Odetta Marks is from the Witches Coven in London. She also leaves home to protect her rapidly decreasing Coven.

Lastly, 18 year old Jenova Santana. Born 1912, she is a vampire from Athens, Greece, and on a daily basis her Coven are moving or being killed.

This unlikely trio, who would usually be enemies, will emerge. They will have to work together to stop humans eliminating their races and protect them.
Will they succeed?
