Huyang was an ancient droid, stooped with age yet still spry of mind. Huyang was a storied architect and professor, who oversaw the construction of lighstabers for centuries. Based out of the training vessel Crucible, Huyang guided younglings after they had successfully completed their task of securing a kyber crystal from the icy caverns of Ilum. At this point, students needed to use the Force to assemble their lightsaber components around their Force-imbued crystals. Huyang helped them visualize their lightsaber parts, and pulled the needed supplies from his vast trove. Huyang navigated his supplies with additional ventral manipulators that extended from his dorsal surface. His ancient memory systems contained records of every lightsaber constructed.
