The Orso system, known as Qab in Sangheili, is a planetary system located within the Orion Arm of the Milky Way galaxy. It is located within the Isbanola sector of the human sphere and contains the human Outer Colony of Venezia. Orso is located in proximity to the Shaps and Cordoba systems, which, along with the Elduros and Sverdlovsk systems, are connected to Orso by the Via Casilina Trade Route.
Although Halo: Warfleet establishes "Orso" as the system's human name, in previous fiction (Halo: Last Light, Halo: Smoke and Shadow, and Halo: Retribution) human characters, as well as the headings for chapters from a human point of view, still exclusively use the name Qab.
