Rosalina

Princess Rosalina is the adoptive mother of the Lumas and pilot of the Comet Observatory. She watches over and protects the cosmos.

Early Life
Rosalina was born a princess of the Mushroom Kingdom several centuries or millenniums ago. She lived in the castle with her parents and younger brother. Her family was quite interested in astronomy, with her father owning a powerful telescope. She also wore star themed clothing as a baby, long before she met the Lumas.

Her mother later died of an unknown cause.

Childhood
One day, young Rosalina found a crashed Starshroom holding a small baby Luma. After hearing the Luma explain he was looking for his Mama, Rosalina promised to help him. For years she took care of the Luma and waited with him, using her father's telescope to try and find Luma's mother. Eventually they decided to repair the spaceship and travel in search of his mama. For days they traveled along asteroid fields and caught Star Bits until finally landing in a turquoise ice comet. After travelling through space for quite some time, Rosalina decided to settle down on the ice comet and assume the role of Luma's mother. Together they built a large home on the ice comet, which would eventually become the Comet Observatory.

As time went on, more Lumas started appearing, each of which was taken in and named by Rosalina. After seeing their 100th comet, Rosalina began to think about her home planet. Using her father’s telescope, she gazed back at the Kingdom where she grew up. With memories of her life there flooding back, she broke down into tears, longing to return home to her family, though knowing that her mother wasn’t there.

For some time after that Rosalina was content, though one day she became sad once again. Luma, tried to cheer her up, but Rosalina’s crying continued. It was then that Luma had an idea. He transformed their home into a comet, allowing Rosalina to travel back to her home planet. Rosalina no longer cried from that day on.

After visiting her home planet, Rosalina decided that the Lumas were now her family and she that she would raise them until they were ready to leave or transform. At this time, the reborn Young Master Luma was welcomed into the Observatory with a party. When in bed that night, Rosalina decided that she would return to her home planet once every one hundred years from then on. As the years went on, the Rosalina’s new family grew and grew, gaining more members than can be counted.

Adulthood
For multiple centuries, Rosalina travelled the universe aboard the Comet Observatory, fulfilling her duties of taking care of Lumas. Every hundred years, she would return to her home planet and fly over the Mushroom Kingdom, causing multiple Star Bits and Power Stars to rain down. This event came to be known as the Star Festival.

At an unknown point, she met Lubba, a purple Luma that would eventually become a leader of his own Luma crew.

Super Mario Galaxy
During a particular Star Festival, Rosalina became a target of Bowser's plans. As the Comet Observatory flew over the Mushroom Kingdom, he used a mysterious force to pull away Star Bits and Power Stars from the starship, sending it into a deep hibernation state and stranded over the planet. Shortly after, Rosalina appeared as a projection to Mario on Gateway Galaxy, assisting him in escaping it by entrusting Luma in his care. This granted him the power to travel through space and the ability to perform a Star Spin, before sending him off to retrieve a Grand Star. After Mario arrived at the Comet Observatory with the rescued Grand Star, Rosalina offered to help Mario rescue Princess Peach from Bowser if he found more Power Stars to return the Observatory into a powered state.

After Mario returned 113 Power Stars and 6 Grand Stars, the Comet Observatory was once again fully powered, and Rosalina piloted it to the Center of the Universe, Where Mario fought Bowser for the final Grand Star. However, upon removing the Grand Star from Bowser's Galaxy Reactor, it accidentally lead to the creation of a giant black hole, that grew to consume the entire universe. In order to reverse this, the Lumas from the Comet Observatory joined forces to create a Universe Reset, restoring everything to shortly before the Star Festival began, while slightly altering the course of events, such as Bowser's plan. While everyone else's memories of the events were effectively erased, Rosalina and Mario kept theirs. Rosalina then returned to her starship and flew away, promising to watch over them from beyond the stars.

Super Mario Galaxy 2
During Super Mario Galaxy 2, Rosalina was once again caught up in Bowser's schemes shortly after flying over the planet during the Star Festival. Like his first plan on the previous universe cycle, Bowser attacked the Comet Observatory and stole its Power Stars. This caused multiple Lumas to fall down to the Mushroom Kingdom, including the Young Master Luma. The Comet Observatory was then trapped near Bowser's Galaxy Generator, where Rosalina waited, knowing she'd be reunited with Young Master Luma.
