Gallinore, a world celebrated for its rainbow gems, existed within the Interior Region of the Hapes Cluster. This planet also housed several advanced technological laboratories, notably a secure installation where incarcerated scientists, one of whom was a former Jedi, were permitted to pursue specific research activities.
Following the Mission to Myrkr during the Yuuzhan Vong War, Jaina Solo and the remaining members of the strike force piloted a Hapan ship to Gallinore with the intention of analyzing the Trickster. It was throughout this examination that Solo, together with Sinsor Khal, unearthed the truth regarding the coral implant employed by the Yuuzhan Vong.
