A Romulan science officer who works alongside Mirok in 2368 and plots with him to destroy the Enterprise-D once it has finished helping their damaged ship.
Varel is an officer on a Romulan science vessel. She appears in the episode The Next Phase, played by Susanna Thompson.
Her ship has suffered an explosion during a secret experiment, and the Enterprise comes to its aid. Varel works with the Starfleet engineers on repairs while saying as little as she can about what her crew was doing. The experiment was a new kind of cloak that shifts matter out of phase.
In private she and her superior Mirok agree that the Federation ship has seen too much. They arrange for a muon wave to build up in the Enterprise's engines so that the ship will blow apart when it goes to warp. Geordi La Forge and Ro Laren, phased and unseen, overhear the plan, and the danger is removed once they are restored.
