The Kessilian civil wars represent a set of armed struggles that took place within the Kessil system, a system that included the world of Utapau. Despite being a young man, Annikin Starkiller participated in these conflicts.
It is believed that shortly following the conclusion of these wars, Annikin and his father, Kane Starkiller, resided on the Fourth Moon of Utapau, close to their abandoned starship.
Initially, in the preliminary script, Annikin's name was changed to Justin Valor. The world of Utapau was also initially called Ogana. However, both of these names were either discarded or reused in subsequent iterations of the story.
