Livewire was a feral child on Gadrell Major.
When her pack attacked Suzi Palsson and Shanstra, the Sensopath killed one of them. She brought Livewire under her control, feeding on her hate of the invading Phractons. Later, she abandoned the child when the Phracton Secondary proved to be a better energy source.
Swearing revenge for the abandonment, Livewire decided to kill Shanstra.
When Kelzen eventually realised that Shanstra wanted to become the dominant personality once their trinity reunited, she distracted Shanstra through their mental link. This allowed Livewire to kill her. (PROSE: Infinite Requiem)
