Antarcticite

Antarcticite is a rare Gem whose crystalline body can only remain stable and active during the frigid winter months. When all other Gems fall into their seasonal hibernation, Antarcticite stands alone as the last line of defense, patrolling vast frozen landscapes and shattering drifting ice. Known for a soldier's precision and an unshakeable moral compass, this solitary guardian took on the role of mentor to Phosphophyllite during one fateful winter. In a defining act of self-sacrifice, Antarcticite was captured by the Lunarians while shielding the young Gem—a pivotal moment that shattered Phosphophyllite's innocence and set the entire story on a darker, more complex trajectory.
