Inzilbêth was the daughter of Lindórie and she was known for her great beauty. She married Ar-Gimilzôr, but she did not love him, for she was one of the Faithful. Ar-Gimilzôr was their greatest enemy and he did not know that she was one of them.

When Gimilzôr became king, they had two sons - Inziladûn, the older, and Gimilkhâd. Inziladûn was like his mother in both appearance and mind, but Gimilkhâd was drawn to his father.
