Aleksei Dorne was a Human male who served the Sith Empire and later defected to the Galactic Republic during the Cold War.


Born on the capital planet Dromund Kaas, Aleksei and his sister were raised to a highly prestigious Imperial family and rose quickly through the military ranks.

In 3643 BBY, Aleksei contacted his sister when his squad was disavowed by the Empire on Nar Shaddaa. Elara was able to help Aleksei by convincing him and his squad to defect to the Republic.
