In the mirror universe, Elizabeth Sherwood was a 23rd century Human woman who joined the Terran Empire Starfleet in the 2280s. By 2285, Lieutenant Junior Grade Sherwood had been awarded an officer's position on Captain James T. Kirk's USS Enterprise. In that year, Sherwood occupied a forward station while the starship attacked and destroyed the Regula One outpost to hide the theft of scientific data from Carol Marcus, who died in the conflagration. With the gain of physics research from the outpost computer, the Enterprise was able to crossover to the counterpart universe. (TOS - The Mirror Universe Saga comic: "... Promises to Keep")
