Author's note: a few things you should know.
Elsa adopted a daughter in my other {slightly rushed} fanfic, her name is Rosetta and she is seven years old {no she does not have ice powers}
Anthrax is…basically the angel of death with enough power to push Elsa around like a rag doll. Needless to say…He is the main villain in this story
Frozen is owned by Disney. Anthrax and Rosetta are mine
Rosetta was meekly making her way to Elsa's study. She was terrified of what was coming. She slowly walked up to the door. The door seemed like it was staring her down, daring her to knock on the unforgiving wood. So she did. She was silently praying that no one would be there, but to her horror she heard the two words that she dreaded to hear.
"Come in" her mother said gently. She reluctantly went in to face her doom.
"Did you call me, mama?" The little girl asked shyly. Elsa nodded.
"Yes I did, dear. The servants found a broken statue in the hall. Do you know what happened to it?" Elsa asked calmly. Rosetta began to tremble. She didn't know how Elsa would punish her if she misbehaved. But Rosetta certainly did not want to find out anytime soon. On the other hand, Elsa has been so nice to her. She didn't have the heart to lie to her new mother. Tears began to form in her eyes.
"M-mama, I'm sorry. It was an accident. I-I didn't mean to" she whimpered.
"Didn't mean to do what?" Elsa asked softly, not wanting to frighten the girl.
"I broke the statue." Rosetta concluded before she started to cry. Elsa put her daughter on her knee and gently shushed her.
"I know what happened little one. I saw it when it happened. I wanted to see if you would tell me what happened even if it meant getting in trouble. You did the right thing and I'm proud of you. Don't cry sweetie." Elsa soothed while stroking her daughters hair. The queen waited for her daughter to calm down and process what Elsa just said. Rosetta looked up at her mother.
"I'm not in trouble?" Rosetta asked, sniffling.
"Because you told me the truth, no you're not in trouble sweetheart. Accidents happen, dear. That's ok" Elsa said lovingly as she wiped away her child's tears. Elsa gently removed her little girl from her lap.
"Come on, Rosetta. Let's help the servants clean up the mess." Elsa said cheerfully while taking her daughter's hand. They were about to reach the stairway when the noticed Anna.
"How much did you hear?" Elsa asked with a devious smile on her face.
"Uh that depends….what happens if I heard too much or let's say…I dunno all of it?" Anna asked cautiously.
"That's it you sneaky sister, you're going to pay for this!" Elsa threatened. Anna's eyes grew wide in horror.
"Are you going to throw me in the dungeons?" Anna asked timidly.
"Worse!" Elsa snarled, trying to fight a grin.
"Are you going to have me executed?" Anna trembled.
"Even worse" Elsa growled.
"are….are you going to shut me out again?" Anna said, trembling. Elsa blinked, caught off guard by that question.
"Oh good heavens, no I would not do something that cruel." Elsa said much to Anna's relief. Elsa formed a huge snowball. Anna was about to run when Elsa simply dropped the snowball into Rosetta's hand.
"Go get her, Rosetta" Elsa cackled.
"Oh no..no no no no no. You wouldn't throw a snowball at your poor old auntie An-" Elsa's baby sister was cut off by a face-full of snow. Elsa laughed along with Rosetta.
"Ok, my little sister, why don't you come with us? We are going to clean up the rubble in the hallway." Elsa asked Anna.
"Auntie Anna, do you want to build a snowman?" Rosetta asked the Princess.
"Elsa…she is a girl after my own heart. But that depends on your mom." Anna hinted towards Elsa. The two of them practically ganged up on the poor queen. The latter shook her head with a smile and sighed.
"Of course, but not until the mess is cleaned up" Elsa answered leading the two younger girls to smile in delight.
The mess was cleaned and the three had a winter wonderland in the ballroom.
"Mama this is so f-"Rosetta was interrupted by a snowball to the face.
"Payback!" Anna said happily. Elsa and Rosetta smirked and Elsa made a huge fort with cannons all pointed at Anna. Rosetta waved to her aunt. Anna just stood slack jawed as she dropped the comparatively puny snowball she had in her hand. Sometime later Rosetta and the Queen managed to dig up Anna from under a pile of snow approximately ten feet in height Elsa noticed her little daughter yawn. She also heard the clock strike eleven.
"It's time for bed, both of you." Elsa said with a smile.
"Aw, mama we are having so much fun. Do we have to?" Rosetta asked rubbing her eyes.
"Yes sweetie. There is always tomorrow to play." Elsa said tapping her daughter in the nose, making her giggle. She then collected her precious charge and carried her to her room.
"Goodnight, Rosetta." Elsa chimed while tucking her in.
"Goodnight mama" Rosetta chirped. Elsa gave her a kiss on the forehead and quietly left the room.
Oh man my OC is really going to shake things up.
