Sapphire of the Stars

I'm Ahoskinson 95 (AKA Sapphire of the Stars). I am a Blue Luma named Sapphire of the Stars.

Luma Life
Sapphire of the Stars was born on the Comet Observatory shortly before Mario's visit. He guarded the Fountain at the Comet Observatory. He had three siblings: Opal of the Stars (Pink Luma), Ruby of the Stars (Red Luma), and Topaz of the Stars (Yellow Luma). His mother was Emerald of the Stars (Green Luma) and his father was Amethyst of the Stars (Purple Luma and Prankster Comet Know-It-All).

Super Mario Galaxy
Sapphire was very "patriotic" of the Comet Observatory and loyal to his "mama". He helped Mario and Luigi whenever and however he could, wanting to restore his home and Rosalina's happiness. He sacrificed his life during the destruction of Bowser's galaxy to save Mario and Peach. He was eventually reborn and returned to the Comet Observatory as official "Guardian of the Fountain".

Aftermath
Sapphire spent the next few centuries on the Observatory, but later became a galaxy called "Sapphire of the Stars" (after himself). This galaxy contained many planets, all oceanic and icy.
