The Eye of Midnight is a magical gem that appears in the Elena of Avalor episode "The Scepter of Light". This spherical gemstone is infused with the Powers of Darkness. These Dark Powers are so potent that those who use Dark Magic can use it to plunge any area into eternal darkness. Centuries ago, the evil moth fairy Orizaba tried to use the Eye of Midnight to do just that to Avalor, but she was stopped by a Maruvian wizard and banished to the Spirit World.
Afterwards, the wizard then hid the jewel away in a Maruvian Temple. Centuries later, Orizaba returned and reclaimed the Eye of Midnight. Placing the Eye in the center of the Sun Stone, Orizaba froze the solar eclipse in place. But in the end, Princess Elena sent the wicked fairy back to the Spirit World and destroyed the Eye of Midnight with the Scepter of Light.
