Ship (The Mad Woman in the Attic)

Escape from the past
Ship was an AI designed by Eve's people and placed on the escape craft with Eve when she was still small with instructions to protect the girl and teach her to control her powers properly by Eve's parents who sent her away from there planet that was targeted by an unkown enemy in a great war (Possible the Time War and the Daleks being the ones who attacked Eve's people).

The pair traveled for a long time before an unkown event caused Ship to crash land on Earth, burring it self under a tone of sand and causing massive damage to its systems. The damage left Ship severly weekned so she was unable to care for Eve untill her systems rebooted which would take about 20 earth years (Give or take). This would pose a problem because the imense power Eve posessed meant that untill she was old enough and instructed properly to control her powers she would be a danger to her self and anyone around her. Fortunatly the pair were discovered by the caretaker of the local fun fair Harry who after being tolled the suituation by Ship was willing to help and raised Eve in confindes of the Fun fair Park were she would be safe and able to practice controling her powers by manipulating the rides at night.

The Red Demon
Unfortunatly has the years whent on Eve (Who while looking like an adult was still technically a child by her species standerds) became increasingly lonely and began to kidnap homless people who wandered in to the park at night because she wanted friends.
