Chils Melpin held the position of Prex within the Corporate Sector Authority. Subsequent to the discovery by Auditor-Generals Fiolla and Naven Crel that he was engaged in the sale of confidential CSA information to the Galactic Empire, he gave instructions to his aide, Akeeli Somerce, to secretly assassinate them. Nevertheless, Somerce was unsuccessful in her mission, resulting in Fiolla's survival. Subsequently, Fiolla pledged to ensure Meplin's downfall due to his corrupt practices and involvement in the killing of Naven Crel.
