It could mean a story that is full of wonder and magic, just like the colors of a rainbow. Maybe it's a story that has no boundaries and can keep going on forever, filled with all kinds of amazing adventures and characters.
One could start by describing the rainbow in great detail. Maybe talk about how it arches across the sky, the vividness of its colors. Then introduce a character who is drawn to the rainbow, like a curious child. And from there, start building the story around the idea of something that never ends, perhaps a magical journey that the character embarks on within the rainbow.
Once upon a time, there was a Spirit Sword Mountain ending that could be referred to as the following story ending:
On the peak of Spirit Sword Mountain, Donald and Amelia finally met. They hugged each other and took a deep breath.
Donald told Amelia that he had not told her the truth because he was afraid she would reject him. But when he truly faced his heart, he realized that he had always loved her deeply.
Amelia also told Donald that she had always loved him, but she was afraid to face the truth. In the end, they finally expressed their love for each other and decided to be together.
Together, they walked through the Spirit Sword Mountain, through the grassland, through the snow mountain, and finally came to the seaside. There, they decided to start a new life and face the challenges of the future together.
Their love was as bumpy as the Spirit Sword Mountain, but in the end, they met at the top of the mountain and embraced a beautiful future together.
In this fanfiction, Belle could convince Rumpelstiltskin to leave his life of dark magic behind. She shows him the beauty of a simple life, away from all the deals and power - hungry individuals. They could move to a small village and start anew, with Rumpelstiltskin using his skills for good, like making beautiful fabrics for the villagers.
It's not based on true events. The movie blends various elements to create a fictional narrative set in the Hollywood context. The characters and plotlines are crafted for entertainment rather than being true to life.
