After the tragic event that has happened to the peaceful kingdom of Arendelle 3 years ago, the snow queen Elsa has continued her duty as queen and kept her kingdom in check and maintained peace. She spends her free time with her sister Anna, and sometimes go to her newly constructed training field where she practices using her divine ice powers for combat and for defense if a problem ever faces Arendelle in the future.
While out training with her little snowman friend with a happy nature Olaf, Elsa's sister Anna rushes towards them nearly out of breath with a very happy expression on her face. "Anna, you looked like you saw a ghost that has been chasing you for hours," Elsa said. "What happened?" After catching her breath, Anna shouted, "KRISTOFF HAS PROPOSED TO ME!" She showed Elsa and Olaf the beautiful diamond ring that was resting on her ring finger. "Anna that is amazing," Elsa replied with happiness. Olaf was jumping for joy and dancing around of this moment. "That is so cute Anna," he said. "What is a propose?" he wondered. "Its when a person asks for a person's hand in marrage Olaf," Elsa explained.
After spending the rest of the day with her sister and coming up with some plans for the wedding, Anna returned to her room with excitement and joy that she will be with Kristoff forever. "I can't wait for the day me and my loved one will be together forever," she said to herself while she was staring out of her window, which happened to face the mountains. "I wonder how Kristoff is doing after he proposed to me?" But before she could leave to find out, she noticed that something is happening to the forest under the mountains. "Whats going on with the trees?" she wondered. "They are becoming frozen. Is Elsa doing this? No it can't be."
Anna began to dash her way to Elsa's quarters to bring her the news of what she saw. Upon entering her chambers, Anna noticed that her sister was fully aware of the frozen forest. She saw the forest becoming frozen as well. "Elsa, are you seeing this?" Anna asked. "Not only am I seeing this," Elsa began. "I can't believe this either. This isn't me doing this. There's bound to be someone or something else doing this. Come on, we need to investigate." She later informed the guards that the forest is becoming frozen with an unknown purpose. She informed them that she will investigate this, but she may need backup. So, her best guards were sent to protect Elsa and Anna at all cost.
Meanwhile in the mountains, a man was moving towards the kingdom, with ice freezing the trees behind him. He was wearing a cloak that covered his body and hid his face in the shadow under the hood. He stood at about 6ft. 2 inches with his fist clenched. Ice has been flowing out of his fists with a serious nature. He has been coming down the mountain by using his powers to make his pathway an ice trail. Upon reaching the main entrance to the kingdom, he whispered, "I finally found it, the kingdom of Arendelle."
