Mira, voiced by Emily Berry, appears in The Sith Lords. Mira lost her family during the Mandalorian Wars. By the end of the wars, the Galactic Republic was flooding with refugees, and many of them, including Mira, ended up in the refugee sector of Nar Shaddaa. To survive in the hostile environment, she became a bounty hunter with the sole purpose of earning credits. A rival bounty hunter, the Wookiee Hanharr, was employed to hunt her by an unknown person. Mira will only join the light-sided player, and can become a Jedi Sentinel.
