Ensign Sariel Rager was a 24th century Starfleet command division officer and helmsman.
In 2367, Ensign Rager was at the conn of the USS Enterprise-D when the ship encountered a swarm of a spaceborne species, of which Junior was a member.
She was at the conn when the ship became trapped in a Tyken's Rift. Lack of dreams caused her to forget how to operate the conn, so she was ordered to sickbay by Commander Riker and replaced by Kenny Lin.
In 2369, Rager was serving aboard the Galaxy-class starship Enterprise-D when the ship discovered a Dyson sphere. She piloted the ship out of the sphere by executing a 90-degree roll to slip out of the quickly closing bay doors.
Following disturbing behavior at the conn, Rager was abducted by Solanogen-based lifeforms and was experimented on in their laboratory. Fortunately, she was saved by Commander Riker.
