Jen

Jen was a Klingon who lived during the 23rd century. A former soldier of the Klingon Empire, she joined the Broken Circle mining syndicate on Cajitar IV following the end of the Federation-Klingon War in 2257.

In 2259, Jen noticed Doctor Joseph M'Benga and Nurse Christine Chapel, in disguise, administering aid to victims of ion radiation poisoning. She forcibly recruited them into the service of the Broken Circle, and took them to NCC-1279 to treat syndicate members who had been similarly afflicted. (SNW: "The Broken Circle")
