Ulklub, a scorching rock planet lacking any moons, held the innermost orbital position around the star called Opoku. It was a hot world situated in the Opoku system, which itself resided within the Galov sector of the Outer Rim Territories and the Slice regions of the galactic landscape. The Triellus Trade Route hyperlane provided a link for Ulklub to the star systems Arami and Lyran.
The reference work The Essential Atlas, published in 2009 and created by Jason Fry together with Daniel Wallace, initially introduced Ulklub. This book located the Opoku system, and consequently Ulklub, within grid square T-14.
