Gbu's high-gravity atmosphere made Gbu uninhabitable to any species unadapted to such an environment. The planet was home to the Veubgri, an insectoid species species prized as valuable laborers able to work in highly pressurized atmospheres.
Discovered during the expansion of Xim's empire circa 25,100 BBY, Ank Ki'Shor was gathered into the Keldrath Alignment nearly a century after Xim's death. It was eventually part of the Tion Hegemony when the Tion Cluster joined the Republic.
In 14 ABY, Gbu was visited by New Republic Chief of State Leia Organa Solo, shortly before her children were captured on Munto Codru by agents of Hethrir. During the visit to Gbu, the New Republic delegation was forced to meet with their Veubgri counterparts on a satellite due to the intense high gravity pressure.
