The Twili are a race of shadow beings who inhabit the Twilight Realm in Twilight Princess. Although usually a peaceful tribe, the Twili are transformed into hideous creatures known as Shadow Beasts by the Usurper King Zant, used to invade Hyrule. Link is able to return several of them to their normal forms when he encounters them in the Twilight Realm. He is even aided in his quest to stop Zant by Midna, a Twili and the princess of the Twilight Realm.
