(coexisting on another dimensional plane)
Commander Ellen Landry was a female Terran Starfleet officer who lived during the mid-23rd century. She was one of the most trusted followers of Gabriel Lorca, assisting him in his coup against Emperor Philippa Georgiou.
After Lorca's coup was defeated and he was presumed dead, Landry was captured and held in an agony booth on board the ISS Charon. She was rescued by Lorca when he returned from the prime universe, and she helped him in overtaking the Charon.
