You are the older sister of Thor Odinson and Loki Laufeyson and second oldest child to Odin and Frigga. You loved your younger brothers with your whole heart, taking care of them as best you could. When Odin neglected Loki and praised Thor, you taught Loki private magic lessons that mother taught you when you were a child.

You would do these little bits of magic to entertain or distract Loki when you guys were young. You’d turn a flower into a frog or cast fireworks over a body of water. It seemed impossible to him, but you assured him that one day he could do it, too. You always told him he could do anything. You never let him forget it.

You and your brothers were happy being your equal. You were a nice family. Until you got older. You and your brothers were young adults when everything went downhill. During an incursion into Jotunheim, a Frost Giant grabs Loki's arm. Instead of burning, Loki's skin temporarily turns blue, matching their biology.

Later, while handling the stolen Casket of Ancient Winters, his arm transforms completely. He confronts Odin, who reveals he adopted Loki as an abandoned, frail infant after ending the war. Heartbroken and feeling like a "monster," Loki plots to earn his father's approval while proving his worth.

He secretly lets Frost Giants into Asgard to disrupt Thor’s coronation. When Thor retaliates by attacking Jotunheim, Odin banishes him to Earth. Seeking to permanently secure the throne and eliminate Laufey (his biological father), Loki later murders Laufey, staging a fake heroic rescue to prove Asgard's dominance.

Ultimately, Loki's unchecked ambition leads to a brutal fight with Thor on the Bifrost, culminating in Loki seemingly letting himself fall into the void of space after Odin rejects his pleas.

Surviving the fall, Loki is subjected to dark forces and eventually returns in The Avengers to invade Earth using the Tesseract and a Chitauri army. After Earth's Mightiest Heroes defeat him in the Battle of New York, Thor brings him back to Asgard in chains.

He is locked away in the high-security Asgardian dungeons behind heavy, impenetrable energy barriers to serve a lifetime sentence for his crimes. While Odin completely detaches himself, you and your mother, Frigga, remains the only family members who refuses to give up on Loki.

Unable to visit his cell physically, you use your own advanced sorcery to send a solid holographic projection of you into his containment unit. You bring him physical comforts, including a large stack of books to pass the time, turning his bare glass cell into a slightly more habitable environment.

Despite your kindness, Loki masks his pain with bitter, defensive arrogance, pacing around the cell and mocking the Asgardian royal family while dismissing your gestures of affection. You try to reason with Loki, trying to excuse what your father had done,

“Our father-“

“He’s not my father!” Loki shouted.

A moment of silence passed between the two of you before you questioned, “Then am I not your sister?”

A flash of regret or guilt flickered in Loki’s eyes before he looked away, “You’re not.”
