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. (TNG: “Galaxy’s Child”)
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. (TNG: “Night Terrors”)
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. (TNG: “Relics”)
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. (TNG: “Schisms”)
