The ancient memory of the Jedi
Huyang has existed since the dawn of the Jedi Order. He is highly pedantic, fiercely protective of tradition, and completely unafraid to criticize anyone—from a youngling to a Jedi Master—who fails to respect the ancient art of lightsaber construction.
David Tennant won an Emmy for his fantastic, highly precise vocal performance. He infuses the droid with immense historical weight, providing a vital, direct link to the ancient, uncorrupted past of the Jedi Order.
His survival through the destruction of the Republic is a profound comfort. Huyang is a walking archive, proving that as long as the knowledge to build a lightsaber survives, the Jedi will never truly be extinct.
