Running from the death penalty, this vampirc male is hiding out in the safety of Septimo for the free food and women. Unlike most vampires this male is a Nehirgy Vampire. A rare breed of vampire where they need moonlight to live. Fumaii, also being of the same rare race took a brothering instinct to Jack and has gone almost everywhere with the boy since they first met. Holding four forms where mother vampires of his kind hold only 3, he has the added benefit of turning into a child. In this form he manipulates others who hold a mothering instinct to be able to feed from there blood stream. This form, as his fangs are as thin as a needle, leaves no trace or pain so no mater how strong ones senses, they can not predict that this is what the young boy is actually doing when he is suckling on there skin. Jack names his child like form Jacku, and claims him as a sibling to anyone that see's Jack in his normal form. This is because Jack is increadibly weak and cannot hold a large form for to long, the fact he has this child form is more a development for survival.
