Natasha and Crystal meet up with witches, vampires and many strange aliens as they pursue their quest with them at the start of the journey is a android called Foster, a goblin called Shimick and Shanice a teenage witch. They travel back where the witches began, at their origins in Scotland. They were said to have obtained their powers as a result of super nova in space, this caused meteors to hail from the skies containing high levels of gamma radiation, which as a rule would be harmful to anybody. The energy omitted from the rock gave them great powers that they were unable to understand or appreciate in some cases, this caused a division in the tribe of cave dwellers resulting in the introduction of two kinds of witches, the white witches who were peace lovers who used their powers for good and the dark witches who were evil and used their powers to destroy and dominate other species.
