Lawrence Miles was inspired to create the Faction Paradox series through his deep interest in time and reality, which he explored in his contributions to the Doctor Who expanded universe. According to an interview with Ninth Art, it was during his work on Doctor Who novels such as "Alien Bodies" that he began to formulate the ideas that would lead to the creation of Faction Paradox. The themes of paradox and the complex interplay between time travel and reality were central to his creative vision. You can read more about it in the Ninth Art interview.
