(Author's Note: This is a preview of an AU in which Anna has fire powers, takes over Arendelle's throne, and decides to take advantage of Hans' intentions to benefit herself and her kingdom financially. The main pairing will be Kristoff/Anna, but it will have darker dashes of Hans/Anna. Please favorite and review if you'd like to see more. Thanks!)
Deep in Anna's chest, something glowed a fiery orange, shining through the layer of ice that encased her. Blackness seeped back into her pupils, her irises contorting into a golden yellow. All at once, billows of steam rose from her statuesque form, the ice sliding down into the ground and forming a large puddle before vanishing completely. The wooden hull of the boat that lingered beneath them began to peek through, then turned an ashen brown as it began to scorch, filling the air with the smell of smoky firewood.
Finally, slowly, painstakingly, Anna lowered her arms. As she did so, the swirling moss green of her corset twisted into a deep scarlet, the gold trim shifting constantly through all shades of fire. Her sleeves matched the gold, glittering against the ice that covered the landscape. Her blue skirt seemed to melt, lengthen, pool around her feet like lava. It was a deep, obsidian black, accentuated with swirls of all shades of glowing red, orange, and yellow. Her molten train glowed with the heat of a hearth against deep black velvet.
She was fire, and she was magnificent.
And as her sister met her gaze, something warm lingered deep in Anna's eyes- No, not warm. Warm was a fireplace, a new coat, the embrace of a loved one. Hellfire was lurking in her eyes. But Elsa clung to her nonetheless, even as her eyes watered and every atom in her body screamed for her to let go of the girl who felt like pure lava.
"I love you. Thank you. Thank you for fighting for me." Elsa sobbed through the pain, holding tight to the sister that was white-hot to her touch. But suddenly, Anna was sliding from her grip, away from her, and the cold that had never bothered until this moment set back in.
"If you won't fight for me like I fought for you," Anna whispered, "I will fight for myself."
Tears ran down her cheeks, leaving dark red stains where they rolled. She turned her back to the blonde woman who trembled at the terrible sight of her, beginning to stride toward the castle that had housed her for so many years. The ice melted as she stepped, and steam seemed to propel her forward. Elsa held out her hand, reaching, straining, struggling to stay on her feet as her knees felt they might collapse beneath her again. Kristoff was rooted to his spot, like a petrified oak.
"And you."
The fiery girl stopped mere inches from the prince that had been her "love" up until minutes before. Hans' face was nigh unreadable, a contorted mix of awe and terror. Anna raised a delicate hand to his face, gripping his chin. Hans whimpered and stooped, but didn't dare to move away from her, no matter how her touch scorched him.
"You wish to be king." Anna's entire body shook with barely-contained rage, but her voice was measured, full of power. "But you will not be the king that you want to be." she leaned in close to snarl in his ear, her breath nearly hot enough to blacken his ears, "You will be the king my people and I need you to be."
