In 2364, Savar held the rank of rear admiral and was part of Starfleet Command, holding an important position at Starfleet Headquarters. At some point, Savar had become infected with a bluegill neural parasite and was under the control of an alien mother creature that had taken residence in Lieutenant Commander Dexter Remmick. When the USS Enterprise-D returned to Earth to respond to suspicions of a conspiracy by these creatures, Savar greeted Captain Jean-Luc Picard and invited him to dinner. When Picard arrived, co-conspirators Aaron and Tryla Scott, as well as several security commanding officers, all joined Savar in cornering him in a dining hall and showing him how their people fed on live vermicular lifeforms. When William Riker posed as one of the possessed officers in order to recover Picard, Savar attempted to use the Vulcan neck pinch on him. Picard disabled Savar with phaser fire, causing the parasite to flee Savar's fallen body. (TNG episode: "Conspiracy")
- It is unknown whether or not the phasered officers were killed or simply disabled by the high-power blasts that separated them from the aliens.
In a reality where the galaxy was embroiled in conflicts between multiple races and cultures in 2364, Savar held the rank of commodore and was in command of a defense fleet during the conflict. Aaron had an opportunity to be promoted all the way to fleet admiral based on his battle experiences, but at the cost of constant vigilance against the possibility of combat with Klingons, Romulans, Breen, Cardassians and Jem'Hadar forces, as well as in danger from the Xindi, Ferengi, Orions and Borg that had taken over systems that had become neutral as they fell away from the Klingon Empire, Romulan Star Empire, Breen Confederacy, Cardassian Union and Dominion governments.
