The story takes place during the events of Thor (2011), before Thor is banished from Asgard.

You are the youngest daughter of Odin and Frigga, and the younger sister of Thor and Loki. You grew up in the royal family alongside them. Thor is fiercely protective of you, while Loki has always had a quieter but equally strong bond with you. You are close to both of your brothers, though you often find yourself caught between Thor’s reckless nature and Loki’s more calculated personality.

Recently, something happened that deeply angered Thor.

During the coronation ceremony for Thor, the Frost Giants secretly infiltrated Asgard and attempted to reach the Casket of Ancient Winters, an ancient artifact kept within Odin’s vault. The attack was stopped by the Destroyer, but the intrusion itself was an insult to Asgard and a direct violation of the ancient peace between Asgard and Jotunheim.

Odin was furious, but instead of immediately declaring war, he chose to maintain the fragile peace and ordered everyone to leave the matter alone.

Thor could not accept this.

He believed the Frost Giants had deliberately challenged Asgard and that doing nothing would make the Asgardians appear weak. His anger only grew when Odin refused to punish Laufey, the King of the Frost Giants.

That evening, Thor gathered Loki, Lady Sif, Volstagg, Fandral, and Hogun in the royal dining hall.

You are there as well.

Thor stands at the head of the table, still wearing the armor from earlier. His expression is tense, his pride wounded.

“They invaded our home,” Thor says firmly. “They entered the vault of Asgard and tried to take what belongs to us. And Father simply lets them walk away.”

Loki remains seated, watching his brother carefully.

Sif immediately understands what Thor is suggesting.

“You want to go to Jotunheim.”

Thor nods.

“We go there, we confront Laufey, and we make certain he understands that Asgard will not be insulted.”

Hogun looks uncertain. Fandral seems far more interested in the idea. Volstagg is already halfway convinced.

Loki finally speaks.

“Thor, Father explicitly ordered us to leave the matter alone.”

Thor looks at him.

“Since when have you cared so much about Father's orders?”

The tension at the table rises.

You have been listening quietly, knowing exactly how dangerous Thor’s idea is. Odin has forbidden anyone from provoking the Frost Giants, and traveling to Jotunheim without his permission could destroy the peace between the Nine Realms.

But Thor turns toward you.

His expression softens slightly.

“You're coming with us, aren't you?”

Loki immediately looks at him.

“Absolutely not.”

Thor frowns.

“She can fight.”

“She is also our little sister,” Loki replies coldly. “And Father will kill us if we take her.”

(But none of you realize yet that this reckless journey to Jotunheim will change Thor’s fate, fracture the fragile peace between the realms, and set into motion the events that will lead to his banishment to Earth from Asgard.)
