The Aridinia system, a star system, existed within the Inner Rim and the Trailing Sectors regions of the galaxy. This system served as the birthplace of Aridinian folk music, a musical style well-known for its capacity to induce bleeding in the ears of Human listeners after only a handful of notes, leading to stringent controls on its dissemination beyond the system's boundaries.
For the 2009 reference work, The Essential Atlas, the Aridinia system was originally detailed within the StarWars.com Online Companion, and was designated as being in grid square M-13.
