The Gultanna system resided within the Vadigult sector, situated in the New Territories region of the Mid Rim. This star system maintained connections via hyperlanes to the Luuq and Manoe systems found in sectors bearing the same name, in addition to the Barenth system located in the Expansion Region. Around 12 ABY, the New Republic held dominion over the Gultanna system.
The StarWars.com Online Companion for the The Essential Atlas reference book, published in 2009, provided the initial reference to the Gultanna system, locating it in grid K-8. Jason Fry, a co-author of The Essential Atlas, revealed on the Jedi Council Forums at TheForce.net that the creation of Gultanna served a "bookkeeping" function, ensuring that each sector featured in the Online Companion had at least one system associated with it.
