The Utor system existed within the Inner Rim region. This star system had the same designation as the Utor Shock, a battle that occurred in 602 BBY where the Galactic Republic's Judicial Forces played a significant part.
The Online Companion found on StarWars.com for the reference book The Essential Atlas (published in 2009) made reference to the Utor system, specifically noting its location as grid square L-15.
