Derran Tal was a Varro female who was an assistant engineer on a generational ship.

In 2375, she became romantically involved with Ensign Harry Kim. This affair violated the rules of protocol, and when Captain Janeway found out, she ordered Kim to break off the affair.

Meanwhile, a Varro was found hiding on the USS Voyager who explained that many Varro felt imprisoned on their ship and wished to leave, and that a violent dissident group was forming to help those who wish to break away. The Varro ship and the Voyager were infected with a synthetic virus that caused microfractures in the ship's hull. Tal revealed that she developed the schematic for the virus, and that she was part of a dissident group that wished to dismantle the linkage that bound the segments of the Varro ship together. The segments which were separate ships could then stay or leave as they wished.

When this had been accomplished, Tal said goodbye to Kim since the more time they spent together, the harder it was to part due to a chemical reaction called olan'vora. (VOY: "The Disease")

Derran Tal was played by actress Musetta Vander.
She filmed her scenes on Wednesday 11 November 1998 and between Friday 13 November 1998 and Wednesday 18 November 1998 on Paramount Stage 8, 9, and 16.
Her costume was later sold off on the It's A Wrap! sale and auction on eBay. [1]
