Graxitium, a unique element, was extracted via mining operations by the Sakiyan species (a sentient race) on Sakidopa, their planetary colony. This exotic substance, graxitium, played a crucial role for the Sakiyans in the creation of repulsorlift circuits. The Sakiyans employed a clandestine technique to refine graxitium at a site situated in proximity to the Godsheart, a pulsar.
The element graxitium made its debut in Lords of Nal Hutta, a 2015 sourcebook for the Star Wars Roleplaying game. This book is part of the Star Wars: Edge of the Empire roleplaying game system, which was published by Fantasy Flight Games.
