In Star Trek: Theurgy, Starfleet Command has been compromised by an unknown enemy, replacing the people in the upper echelons of this institution, which is the Commander in Chief, the Chief of Staff, and the Chief of Starfleet Operations. It is unknown what other bodies of power in the galaxy have been infested with the alien influence.
