Leanneth was most recently discovered to have been the demon hired by the Federation to direct their attempts to dig to the core of the planet of Edwardiana. It was significantly noted that after the defeat of that enterprise by the forces of the British Empire, Leanneth widely publicised that she was no longer under contract to the Federation, and was available for hire.
