Twili
From Zelda Wiki, the Zelda encyclopedia
The Twilit are the race of beings who inhabit the Twilight Realm. Most of the inhabitants are of the "monster" variety throughout your adventure, due to Zant's evil rule.
The Twilit were a race that was sent to the Twilight Realm by the Sages of Hyrule. They were sent there for crimes of unknown origin. Midna became the Twilight Princess, but was overthrown by Zant toward the beginning the of The Legend of Zelda: Twilight Princess.
