Happy Valentine's Day, everybody! I wish happiness to every couple in the world, in the series and movies. I'm still single, but I keep hoping that one day I'll find love.


Hours had passed since Korra and Elsa had gone to the ice castle for training. During that time, Anna followed her sister's instructions and was able to keep things in order, of course, Kristoff was there to lend a hand.

During that time, she couldn't stop thinking about her sister. Yes, she was training with Korra, but she couldn't imagine the kind of training the two of them were doing. In her mind, she cursed herself for not having powers like her sister. If she had, maybe things would have been totally different. But that couldn't be, and all she could do was be there for her at all times, just as she had done when she escaped at the coronation party.

At this moment, she was looking out the window at the mountains where the castle was located. Although she was happy for her sister, she would have liked to go with them.

"Anna." her train of thought stopped when the princess heard someone calling. She turned her head and saw her boyfriend approaching her. "Is something bothering you?"

"No. It's nothing." Anna said, lying a little.

"You can't fool me. You were thinking about your sister and Korra, right?" said Kristoff, since he knew his girlfriend pretty well.

"(Sighing) All right. It's just... After what happened with the blizzard thing, Hans and her powers, I was there for her, supporting her through everything. I'd just like to be by her side on this too." said Anna.

"It's also because you want to see the training they're having, isn't it?" said Kristoff.

A nervous smile formed on the princess' face. "Hehe. Maybe." Anna said, seeing that she had been caught.

"Look. I don't know much, but I can tell you that Korra must be doing everything she can to help your sister. In a way she's like you, only more responsible." said Kristoff, saying the last thing as a joke.

"Hey! I've been able to handle things in the queen's absence, just so you know!" said Anna offended by the joke.

"Hehe. I know. I know. It was just a joke." said Kristoff, calming his girlfriend.

Anna tapped him on the shoulder as punishment, but she still smiled at what he did to cheer her up. "Thank you, Kristoff. I needed that." said Anna.

"That's what I'm here for, isn't it?" said Kristoff.

"Come on. Let's check that everything's in order for when they come back." Anna said.

BOOM

Suddenly, an explosion sounded throughout the castle.

"What was that?!" asked Kristoff, surprised and alarmed.

"I don't know, but I'm sure it's nothing good." said Anna before running to investigate.

"Anna, wait!" said Kristoff following her.

The two of them ran through the corridors until they reached the main hall, where they saw something that made them gasp.

The doors of the room were broken, as if something or someone had broken through them, the same thing happened with the windows, but the worst thing was who broke in. Some creatures resembling goblins filled the room, but they weren't goblins like the ones in the books, these were completely black, as if they were shadows that had come to life.

As soon as they heard someone entering the room, they all turned their eyes to the princess and the ice master.

"Uh-oh." said Anna, realizing the situation.

"Run!" said Kristoff holding Anna's hand and starting to run around the castle with the shadow goblins chasing them.

Meanwhile, in the corridors, Olaf and Sven were walking in their thoughts.

"I wonder how those two are doing in their training. I'm sure they're having a great time." said Olaf.

Suddenly Sven stopped as he moved his ears back and forth as if he were hearing something, although that wasn't the case with the snowman.

"What is it, Sven?" asked Olaf.

Not having time to answer the snowman and following his instincts, Sven ran in the direction of the source of the sound.

"Oh. Are we playing hide and seek? Okay! Then I'll count. One, two, three..." Olaf was saying, covering his eyes with his hands, unconscious of the situation that was happening in the castle.

Anna and Kristoff were still trying to escape the horde of shadow goblins that was chasing them. It didn't matter when they ran or how many corners they turned; their pursuers didn't seem to get tired.

Without warning, Anna stumbled and fell to the ground. Kristoff stopped when he saw his girlfriend in danger.

"Anna!" shouted Kristoff.

Anna looked up to see a small group of shadow goblins jumping towards her, she screamed in panic thinking that it was the end of her, but, fortunately, she had fallen near an intersection and from the other corridor Sven appeared, who attacked the attackers, sending them towards the rest who were knocked down like skittles.

"Sven!" said Anna glad that the reindeer came to save her.

"Come on! Hurry up!" said Kristoff, lifting Anna off the ground and placing them both on Sven, who soon fled from the spot just before the shadow goblins rose from the ground, grunted in rage, and chased them again.

The reindeer ran through the corridors of the castle with the shadow elves behind them. He had to use all his strength to keep away, as he had two passengers on him. The chase reached the corridor where Olaf was in the same position as before, but he ignored it and passed it by, the same thing happened with the shadow goblins.

"98, 99 and 100." said Olaf before clearing his eyes. "Well. Ready or not, here I come." said Olaf as he began to walk in search of his 'hidden friends'.

Sven kept running until he reached the main salt. Once he stopped, Kristoff and Anna got off him and quickly closed the doors of the hall (except for the main one which was destroyed). They had to lean against the doors while the shadow goblins knocked non-stop, wanting to get through.

"We won't last long like this." said Kristoff.

"I'm sure Elsa and Korra have heard about the situation and are on their way here. We just have to wait a little longer." said Anna.

Unfortunately, they didn't have enough strength to keep the doors closed and had to step aside when the shadow goblins opened the door and stopped to look at them with angry looks.

"I think they won't wait any longer." said Kristoff as he, Anna and Sven retreated before the shadowy army that was slowly advancing towards them.

"AWAY FROM MY SISTER!" a shouted sounded before a flash of white energy suddenly appeared and a wall of ice formed separating the shadow goblins from them.

Anna and the others turned their heads to see Elsa and Korra enter the room, the former with a worried expression.

"Elsa!" said Anna happy to see her sister arrive on time.

Both sisters ran towards each other and hugged each other as they reached each other.

"I'm glad I got here in time." said Elsa.

"I knew you'd come." said Anna.

"Excuse me." said Korra, making the sisters break up their hug. "I don't want to interrupt this beautiful moment, but someone can tell me what's going on here."

"We don't know. We were with our things when we heard an explosion, when we arrived, we saw these strange creatures that began to chase us." said Kristoff, recounting the events. "By the way, how did you get here so quickly?" he asked, knowing the long distance between the two castles.

"Now isn't the time." said Korra before looking at the shadow goblins trying to break through the ice wall. "Is this a normal thing in this world?" Korra asked.

"Believe me. If it was, I'd be the first to know." Anna said declaring that no one knew anything about it.

"Okay. Here's what we're going to do: Anna, Kristoff, go to a safe place, Elsa and I will take care of these creatures." Korra ordered.

"What? Are you really going to face that whole army by yourself?" asked Kristoff, not believing that they would do that.

"I won't leave you behind-" said Anna.

"Anna. This is very dangerous and I don't want you to be in danger-" said Elsa, putting a hand on her sister's shoulder to reassure her. "And remember. I'm not alone, Korra will fight me-" said Elsa with a confident smile.

Anna looked at her sister and then she looked at the Avatar who had the same smile as a sign that she agreed with her.

"(Sighing)" It's okay. But be very careful." said Anna.

"Don't worry, I will. Besides, it will be a good opportunity to show the result of my training." said Elsa.

"Then give them a thrashing from me." Anna said before she, Kristoff and Sven left the room, but they peeked out a little so they could see the fight that was about to happen.

"Are you sure you're ready? This won't be like the intruders the other night." Korra said.

"I may be a little nervous, but I won't let that stop me from protecting my kingdom and my sister from these creatures." Elsa said with determination.

"All right." Korra said before they both took up battle positions. "Remember the moves I taught you?"

"Quite a lot." Elsa replied.

"Good. Then feel free to use them." said Korra.

The shadow goblins continued to hit and scratch the ice wall until, in the end, they managed to break it down and make their way to the two presents.

Korra began, stretching her arms forward, throwing a gust of wind that split the army in two.

Korra started with a jump, along with a couple of rocks that came out of the ground and then, while in the air, she punched her fist and foot into nothingness, sending the 2 rocks towards some shadowy goblins, who, for some reason, disappeared when they were hit. Which Korra realized.

"Elsa, they're like spirits! If you hit them, they'll disappear!" Korra informed the queen.

"Copy that!" said Elsa after hearing what the Avatar said.

Elsa, waving her hands like a waterbender, impaled several shadow goblins with spikes of ice that emerged from the ground. Then she moved her arms to one side, sending a current of cold air that froze another group of shadow goblin and did the same to the other side.

Korra wasn't far behind either. She placed her hands on the ground and began to spin upside down as she sent a stream of fire through her feet, forming a ring of fire that burned some shadow goblins. When the fire faded and Korra stood up again, she saw one of the armors in the room and using metalbending, she drew the armor to her and modified it until it became a metal ball that sent out another group of shadow goblin.

"You didn't tell me you knew how to manipulate metal too." said Elsa seeing Korra's hidden power.

"I guess I forgot." Korra said.

Then, using waterbending, Korra manipulated the water in her canteen to form eight water whips and turn the tip of each one into ice. She beat and cut off the last remaining shadow goblins with those tentacles until she realized she had eliminated their entire share.

Turning her head, she saw that Elsa had some enemies left. She wanted to help her, but then she thought it would be good for her to get some experience, so she stood by and watched the fruit of her training, though she would intervene if things got worse.

Elsa needed to finish this quickly, but she didn't know how, but then an idea formed in her head as she remembered the training she had with Korra. It could be difficult and exhausting, but she had to try.

She took a deep breath to compose herself and when she felt ready, she turned her arms clockwise with white flashes in her wake as a set of ice blades formed around her. Korra was stunned to see this, as was Anna and the others.

After the circle was complete, she stretched her arms out to either side, causing the swords to take position, then threw her arms forward as she let out a small cry of effort, sending the ice blades toward the shadow goblins. Some failed, but most managed to hit the remaining enemies, eliminating them until there were none left.

After she finished, Elsa lowered her shoulders and breathed a heavy sigh because of the effort she put into that attack. Unfortunately, she couldn't rest long when she saw the Avatar running towards her.

"You did it! You're amazing!" said Korra hugging Elsa, which made her blush a little, both from the hug and the compliments.

" It's... It's no big deal." Elsa said nervously.

"What isn't?" Korra asked. "I've seen all kinds of things during my life in my world, but I've never seen anything like what you just did, it's definitely something to admire." said Korra.

Elsa blushed a little more to hear that, it was the first time she had done something like that and now it turns out to be something admirable and amazing. Her train of thought stopped when she felt her sister suddenly embrace her.

"I knew you'd make it!" Anna said.

"I agree with Korra. What you did was awesome!" said Kristoff.

"How could you think of something like that?" Anna asked.

"Well. During the training, we were practicing creating ice things and moving snow. When I saw Korra manipulating that armor, I remembered that, in a book, I read about how in some battles, archers would shoot a shower of arrows." said Elsa trying to explain how she did it.

"So, you traded the arrows for swords and then sent them to those creatures." said Korra understanding the queen's plan.

"Yes, but it was just a thought, I didn't expect it to work." said Elsa.

"It was still amazing! You both were fantastic!" said Anna.

"By the way. Why didn't you tell us you could control the metal? I thought benders could only bend the four elements." said Kristoff recalling Korra's trick about armor.

"Hehe. I forgot to mention it." said Korra with a nervous smile. "About that. Just like Amon could bend blood, there are some benders who can bend an element that is derived from one of the four main elements, like lightning, lava or metal." said Korra.

"Your world stops surprising us." Anna mentioned.

"Where did these creatures come from?" asked Elsa.

"I don't know. They came out of nowhere." said Kristoff.

"I'm just saying, it's no coincidence this happened shortly after the dance." Korra suggested.

"Are you saying these two events are related?" Anna asked.

"Now that you mention it. When the guards questioned the men, who attacked me that night, they were all confused. Some said they didn't remember anything and others mentioned that they felt like something was controlling them." said Elsa.

"Mmm." Korra said, putting one hand on her chin, analyzing the situation. "So, surely the person who manipulated these men to attack you is the same person who sent these creatures."

"But who would do such a thing?" Anna asked.

"I guess I'll have to answer that." a voice sounded all over the room. For Korra, that voice was unknown, but for the rest, that voice was familiar and brought back bad memories.

"That voice. It... it can't be." Elsa said a little scared.

"Oh, but it is, my dear queen." said the mysterious voice. They all turned in the same direction to see that, on the wall, a shadow was forming that took on a shape familiar to Arendelle's group. "It's been a long time, hasn't it?"

"Hans!" said Elsa in surprise.

"I see you still remember me." said Hans.

"I should have guessed that you were behind all this!" said Anna looking at Hans' shadow in anger.

"I'm surprised you didn't do it sooner." said Hans in mockery.

Anna clenched her fists in frustration. If it wasn't a shadow, I would have hit him in the face again. Kristoff put one arm around her to reassure her.

"So, you sent those men and those creatures, right?" Korra asked. Even though she didn't know who he was, she had to put that aside to focus on knowing more about his intentions.

"My apologies, but I don't think we've met. I am Hans." Hans said politely.

"Korra, and now answer me." said Korra not wanting to be polite to someone who attacked her new friends with dirty tricks.

"That's right. I was the one who manipulated those men into killing the queen during the ball, but I didn't expect you to intervene. No doubt you have exceptional powers, I could say they are even superior to those of the queen." said Hans.

"Stop flattering us, tell us what you want." said Korra, squinting in the shade.

"Well. Since you have been able to wipe out my personal army, I thought you could talk about this in person." said Hans.

"Forget it! We're not playing your game!" said Anna.

"As you wish. If you change your mind, I'll be on the northwest side of the mountain. But I warn you that if you don't come, I will send something worse than those shadow goblins and the target won't be the castle." said Hans before he disappeared from the wall.

Elsa and the others were frightened by Hans' warning and worried about what decision to make.

"Very good. Before I decide anything, I'd like to know how you know this guy." said Korra looking seriously at those in the room.

Elsa and Anna were nervous, as they didn't want to upset the Avatar for hiding information.

"Let's just say he's someone we knew a long time ago." said Elsa.

"Why didn't you tell me about him?" Korra asked.

"Because we didn't think we'd ever see him again." said Anna trying to excuse herself.

Korra sighed as she pinched the bridge of her nose. "That doesn't matter anymore. You have to tell me everything you know and happened in relation to him." said Korra.

The two sisters nodded in agreement, but before they could open their mouths, someone entered the room.

"I found you!" They all turned to the door to see Olaf smiling. "I have been looking for you everywhere. You sure are good at playing hide-and-seek." Olaf said before looking at the mess in the room. "What did I miss?" he asked without being aware of what happened.
