"Ah hah!" Twilight pieced it together, "I found what we need! We need to combine this spell with the amulet, then all will be saved!"
"We need to get back to the amulet!"
Starlight led the charge with Twilight just behind. They would not slow down, even while blistering temperatures in the castle simulate that of an oven.
They visited the amulet on the balcony once again and began their second, and final, attempt.
Twilight's horn lit up and shot the solar amulet with Spherical Prison while Starlight kept it stable. The amulet was brighter as Twilight finished the spell. It started to radiate a teal blue while it continued to shine ever brighter. Unlike the last attempt, it began to spin on its own and shot a radiant ray of light directly at the sun.
The ponies of Ponyville saw this teal light project from the castle. They stopped moving clouds for protection and assembled below the castle's balcony to bask in the spectacle. Slowly, a bubble-like shield began to form around the sun. The sun was still growing, attempting to fight off its captor. Twilight, Starlight, and all Ponyville residents remained still, full of anxiousness as there was nothing left they could do.
The bubble entrapping the sun let out a deep plump sound and resonated a blue glow when it finally completed its task.
The sun had been detained.
"Twilight! We did it!" Starlight shouted in glee as she jumped as if she were playing a game of jump rope.
Twilight had no words for this spectacular moment. She simply sat down and took in the moment. The moment that guarantees that the planet would not be destroyed. The moment that saved millions of lives. The moment that kept the future safe for centuries to come.
The Solar Amulet became white-hot and glowed a resplendent pure white; it was like a miniature star. After reaching its apex of bright intensity, it burst into flames, then disintegrated into ash that floated upon the delicate breeze.
Joyous shouts and celebratory hurrahs quickly came from Ponyville down below.
