In my perspective, Rosalina is a cosmic entity that transcends the traditional Mario characters. Her ethereal existence and maternal role regarding the Lumas suggest she has existed for eons, laden with knowledge and stories far beyond our comprehension. The observatory is not simply a hub for gameplay purposes but her sanctuary, a homage to the vastness of space and her role as a shepherd to the stars. Her story in the storybook is deliberately incomplete to encourage us to wonder and theorize, adding a layer of depth to Mario's universe.

TBH, I never thought too hard on Rosalina's backstory. Always took her as a cool addition to the Mario universe - sorta like a magical figure who doesn't need a detailed origin. The mystery adds to her charm imo!

Rosalina's origin is quite mysterious, but here's my take. Rosalina and the Lumas are possibly from a different dimension where they govern the laws of the Mario universe. Her observatory navigates through these dimensions, which ties into how Mario can travel to different galaxies with different physics at play. Also, the fact that she has this ethereal appearance suggests to me that Rosalina tapped into some hidden cosmic power which altered her state of being. Her mother in the storybook might be a symbolic representation of a planet or even the universe, indicating Rosalina's ascension from a planetary protector to a guardian of galaxies.

Isn't it canon that she visits the Mushroom Kingdom every 100 years? What if she's a time traveler or immortal, and this is just her stopping by in different eras? It would make sense why she's so chill about everything!

Rosalina is clearly Luigi in drag. Change my mind.

So, look, Rosalina is basically space mom right? Her storybook is all about losing her family and then finding a new one with the Lumas. I always kinda seen it as a way to show how people can find family in the most unexpected places. Maybe Nintendo just wanted to give us a character that shows that it’s not the end even when you lose something precious...like a metaphor for hope and stuff.

There's a profound theory I've read where Rosalina is considered the guardian of the universe, akin to a celestial deity in the Mario lore. Going deeper, her connection with the Lumas is symbolic of cosmic creation myths – she ushers new stars and possibly even galaxies into existence. The Comet Observatory isn't just her home, it's a vessel of life and creation, traveling through space and time. I think it's possible that Rosalina was an ordinary inhabitant of the Mushroom Kingdom who encountered a Luma in distress, and through her kindness and willpower, was transcended into a higher cosmic being. Her backstory might remain vague to keep her character shrouded in mystery and intrigue.

always thought Rosalina’s like a future Peach or something. the colors and the theme with stars? gotta be connected. plus the whole cosmic guide thing in Galaxy 2 gives off this vibe that she knows more than she’s letting on.
