Star Trek Expanded Universe

The Mysterious Case of Neelix's Lungs is an AU Star Trek: Voyager fanfic series by StarSword and Worffan101.

The series is episodic, featuring a mixture of rewritten canon episodes and original stories.


The story is set in an alternate timeline where the Caretaker captured Gul Aman Evek's CDS Vetar in addition to the Val Jean. When USS Voyager subsequently goes looking for the Val Jean, it is transported to the Delta Quadrant and the entire senior staff, including Captain Kathryn Janeway, is killed. However, Lieutenant Veronica Stadi, Voyager's conn officer (who was killed during the passage in the canon show) survived with severe injuries and is left acting captain.

They form an alliance with Gul Evek and begin a two-ship journey towards home.
