Sariel Rager

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 (NCC-1701-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 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. 

Apocrypha
The Star Trek: Titan book series sees now-Lieutenant Rager transferring to the USS Titan following the events of Nemesis, having remained with the Enterprise crew following the transition to the Enterprise-E. The novel Death in Winter had stated that Rager was promoted to Lieutenant Commander after Nemesis, taking a post as second officer aboard the USS Hedderjin, under the command of Picard's longtime Stargazer XO, Gilaad Ben Zoma, but this event was later overridden in favor of her role on Titan.
