Denebia was a planet. It could be found within the Denebia system, which itself was part of the Senex sector. The Senex sector belonged to the Senex-Juvex region, located in the Western Reaches of the Mid Rim. This world was near the sector's region called the Tangles. The Senex-Juvex Loop hyperlane connected it to both the Anturus and Kalgo systems. In addition, another hyperspace route provided a link to the Suliana system.
The landscape of Denebia consisted of cool and dry plains. Plantations and towns belonging to House Hax, a aristocratic Ancient Houses family in that area, dotted the surface of this planet. The planet Denebia is also where the game Denebian holo-chess was first created.
The reference book The Essential Atlas first mentioned Denebia in 2009. Daniel Wallace and Jason Fry were the authors of this book, and they located Denebia in grid square L-18.
