It is an exciting day in the Kingdom of Avalor because a solar eclipse is going to take place, which happens over Avalor once every two or three hundred years. For the occasion, Isabel has invented a telescope that can project an image of the sun on a wall, allowing everyone to watch the eclipse safely since looking directly at the sun can hurt people's eyes. She calls it a Solar Projector. While everyone else is excited, Armando is not because he fears the evil moth fairy Orizabba will appear during the eclipse. Long ago Orizabba tried to bring total darkness to Avalor until a Maruvian wizard stopped her and sent her to the spirit world. But it is said that Orizabba found a way to return to Avalor every solar eclipse so she can fulfill her dark plans. While everyone believes it is just a folklore tale, Armando believes it is true.
Later, Elena is getting ready for the eclipse festival, and when she picks up her scepter it glows bright as it always does every time she holds it. So deep in thought about why it keeps glowing for her, Elena trips over a footstool and hurts her foot. She cries in pain "blazes" which suddenly causes the scepter to fire a powerful beam of light that blasts the footstool. Startled by what just happen, she calls upon Zuzo who instantly appears before her. Elena tells him about what just happened, and when she gets to the part where she cried "blazes" the scepter fires another beam of light at one of her pillows. Zuzo tells Elena to put the scepter down and avoid saying "blazes". He takes a closer look at the scepter and after running it through with a few friends from the spirit world Zuzo deduces that her scepter is magical due to its Maruvian origins. Zuzo also notes that the scepter is possibly channeling the magic Elena got from the Amulet of Avalor. He cannot be certain how it works yet, but it is clear that Elena has the power to destroy things with a single word. Zuzo promises to make further investigation, and for the time being instructs Elena to leave the scepter be, despite that she needs it for the eclipse festival.
Meanwhile, everyone is gathered for the eclipse festival and Isabel has the Solar Projector in place. With everything set, it is time for Elena to give her speech but not before Armando shows up with her scepter. She reluctantly takes it and proceeds with her speech, as well trying her best to avoid saying any words that will make the scepter blast things. But as the guards light the torches, the evil moth fairy, Orizabba, appears before them as Armando predicted. Returning to fulfill her goal in bringing Avalor into total darkness.
