Star Wars: The Light and Darkness Wars
Juhani once was a soldier for the 105th Sith Legion however she was not happy with the missions they were doing. The commanding officer in charge of her unit tended to be disagreeable with her as well and as punishment, he would specifically assign her to complete the “dirty jobs” which did not sit well with Juhani’s principles.
Feeling the Sith’s goals were not in her best interests she jumped ship to the Republic side. Juhani now works as a mercenary-for-hire for the Republic. Without the requirements of “following orders” she takes missions she is only interested in; which suits her just fine.
