Twilit

The phrase Twilit is a prefix given to any being or object that has been engulfed in Twilight by Zant, king of the Twilight. Twilit beings will always be hostile towards Link and his affiliates. The most notable Twilit creatures are each of the bosses that appear during the course of Twilight Princess.

In modern English, the word "Twilit" means "lighted by or as if by twilight," referring to the light of the setting sun. In this context, calling a being consumed by Twilight as "Twilit" is more than appropriate.
