In the sunny city of Murcia lived a little girl named Martina with her loving parents, Laura and her brave dad. Martina's world was filled with princesses and unicorns. Every corner of her room sparkled with the colors of rainbows, and plush unicorns guarded her dreams at night.

One starry night, as Martina was tucking into bed, she found a glowing stone under her pillow. 'Take this stone and close your eyes, believe in wonders and big surprise!' whispered a voice softly. Excitedly, Martina held the stone tight and wished to become a princess like in her favorite stories.

In a blink, Martina was no longer in her room but in a lush, green meadow, dressed in a shimmering gown. She had become Princess Vayana! In front of her stood majestic unicorns and her parents, now a queen and king, with smiles wide as the sky. 'Our kingdom needs your help,' they said.

The kingdom was in peril because the stars were fading from the night sky. As they dimmed, so did the kingdom's joy. Princess Vayana, with the help of the unicorn friends and her royal mom and dad, set out on a quest to bring the sparkle back to the stars.

They journeyed past glittering rivers and mountains that touched the clouds. Along the way, Vayana painted signs so they wouldn't get lost and sang songs to cheer up her team. She even played soccer with magical creatures to gain their trust and learn their secrets.

As they reached the darkest part of the forest, they found a mess of fallen stars, tired and neglected. Vayana remembered how she didn't like to clean up at home. But she knew it was important. With a song in her heart, she set to work, and her parents and the unicorns joined in.

The stars began to twinkle again, and soon the night sky was ablaze with light. The unicorns cheered, and her parents hugged her tight. 'You've learned a valuable lesson,' they beamed. 'Helping and listening are more important than they seem.'

With the magic stone's light now brighter than ever, Vayana closed her eyes and wished to return home. When she opened them, she was back in her room, with the morning sun peeking through the curtains. She hugged her mom and dad and promised to always do her part, as a good princess should.
