Though sharing a common genetic history with the humans, Miraluka have evolved into a significantly different species, evidenced by the fact that they are born without eyes. On their homeworld of Alpheridies, the only source of light is a red dwarf star which emits light only in the infrared spectrum. Over the centuries, the Miraluka have adapted and developed the ability to see their surroundings through the Force. Miraluka wear decorative veils to conceal their vestigial eye sockets for social reasons, and generally have little trouble assimilating into human society.
Miraluka have lived primarily in isolation over the millennia, but because of their Force-sensitivity they have had relations with the Jedi with some Miraluka even joining the Jedi Order. That relationship has grown even stronger since the Jedi Civil War when the Sith LordDarth Nihilus destroyed the Miraluka colony on the world of Katarr. The only survivor of that attack - a Miraluka named Visas Marr - was known to have traveled with the Jedi Exile Meetra Surik and later to have helped rebuild the Jedi Order.
In the years since the Great War, Alpheridies has remained an independent system, but many Miraluka have rallied to the Republic's cause. Those who have joined the Jedi Order have proven to consistently be strong in the Force and exceptionally skilled in the martial arts. Some masters speculate that it is precisely because of their trust in the Force rather than their eyes that they fight so fluently with lightsabers. Regardless of where and how they serve the Order, the presence of the Miraluka within the Jedi ranks has been a boon. Many Sith Lords have learned the hard way to see that Miraluka can be dangerous foes.
