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. Huyang helped them visualize their lightsaber parts, and pulled the needed supplies from his vast trove. His ancient memory systems contained records of every lightsaber constructed.
