Iphigin, situated within the Core Worlds' Iphigin system, was a planet and the original homeworld of the Iphigini race.
Within the Core Worlds, Iphigin presented as a planet of bluish-red coloration. It resided in a region populated by the Diamala, bordering the Ishori Confederene, and served as the native planet for the Iphigini. Functioning as a significant trade hub for the New Republic, Iphigin catered not only to its own sector but also to two adjacent ones. For defense, a Golan I platform was in place. All spacecraft entering or exiting the planet's airspace were managed by the Iphigin Spaceport Directorate.
During 19 ABY, Iphigin played host to a conference arranged by Chief of State Ponc Gavrisom with the aim of resolving a conflict between the Ishori and the Diamal. Despite the involvement of Han Solo, Chewbacca, and Luke Skywalker, a resolution proved unattainable, and the disagreement became intertwined with the larger Caamas Document Crisis.
Furthermore, Solo, Chewbacca, and Skywalker assisted in the defense of the world during an attacked launched by the Cavrilhu Pirates.
