Who Is Huyang? Ahsoka's Ancient Lightsaber Droid Explained
In just the first couple of "Ahsoka" episodes, Huyang quickly proves his worth. Because he helped craft every Jedi lightsaber for thousands of years, he's able to access his deep databanks and conjure up some helpful info on Shin Hati and Baylan Skoll. He also offers some kind advice to Sabine in a moment of doubt — something that the old droid has done countless times with padawans over his long life.
However, Huyang's survival is more important than all that. As Ahsoka's quest for Ezra and Thrawn leads her out of the regular "Star Wars" galaxy and into even deeper reaches of space, she could continue to encounter more and more ancient secrets. Over the course of the order's reign, the Jedi forgot way more about themselves and the Force than they ever knew at once. But because of how old Huyang is, he's the perfect guide through these neglected mysteries.
The big question is why Huyang is with Ahsoka instead of Luke Skywalker. The latter is an actual Jedi still, and he's primarily concerned with rebuilding the order. You'd think that someone like Huyang would be an invaluable asset in helping Luke reconstruct things as they were, but perhaps he believes that the search for Thrawn is more important. Or maybe, like Ahsoka, Huyang understands that there are reasons why the Jedi Order fell in the first place.
