Chapter 1: The Quake

(Elsa)

"Good evening, Miss Arendelle." Kai said politely with a small bow as he opened the door to my ice-blue limo. It was parked just next to a cobblestone path leading through a large tundra plant garden up to the front door of a very old mansion. The plants needed to be able to survive in the cold, mountainous environment on which the mansion was built. It snowed almost always, though today was an exception. The sky was clear; the sun was setting behind the mountain range.

The mansion's combination of stone and dark wood gave it a medieval-sort of feel, yet it was rather appealing and well-maintained. Spruce, birch and willow trees were dotted all through its perfectly mowed yard. Two massive willows arched above the garden path to the front door.

I stepped out of the limo and straightened, giving Kai a smile as my glass heels clipped softly on the sidewalk. I was dressed professionally in grey dress-pants and an overcoat with a white shirt underneath, all tailored perfectly. Comfortable as it was, I hated the garb. Most work days I was dressed in simple jeans and a flannel shirt with my white labcoat. But today had been filled with board meetings and other such nonsense that I normally left to my aunt Gerda. Alas, a few times a year I did have to make an appearance as the largest stock holder for Arendelle Inc.

"Good evening to you as well, Kai. Is my sister home yet?" I asked as I started walking towards the front door of Arendelle Manor, my family's home for over ten generations. Two suited bodyguards stood on either side of the front door. Both of them bowed their heads as I passed. I nodded in return and muttered a soft "Good evening, gentlemen," before Kai spoke up to answer my previous question:

"Not yet, Ma'am. She did say something this morning about being close to a breakthrough with genetic splicing. I would assume she has lost herself in her work again. I'd be surprised if she even knew the hour." Kai said with a smile on his face. We all adored my bright cheery sister and I knew Kai, like myself, found her single-minded focus to be seemingly magnetic.

Kai has been the bulter for my family since before I was born. Since the death of our parents three years ago, he has stepped into the role of caretaker for Anna and myself.

"Very well. Please make sure that dinner is sent to her offices. I will take dinner in my own rooms this evening, unless Anna happens to return before it is ready." I turned on my heels and walked up the grand staircase made of white marble, immediately turning left to head down the west wing of the mansion; the residence of my private rooms.

The mansion may have been generations old—in fact, it look more like a castle in some places—but it was kept in perfect order with all the latest technologies and advancements, both for comfort and security.

"Oh Anna…" I mumbled once I was sure I was alone. Anna had been working tirelessly to find a way of mixing the genetic traits of animals in hopes that she could eventually bring traits like those of reptilian regeneration of limbs to humans, or the ability of a certain fish (I am not sure of its name) to regenerate cells on command.

I was immensely proud of my sister for her work thus far; I mean, Anna being only 16 years old, and yet she was the world's leading scientist on genetic research and manipulation. She graduated college at age 14. She has successfully created cross-genetic clones between different species of spiders (an amazing feat by itself) and she now she believes herself close to splicing only desired traits from one species to another.

Proud of my sister or not, I was also worried because she had a tendency to forget to eat and even sleep when she got lost in her work—it seemed like she was tonight.

I may not admit it, but I was a genius in my own right. I've made many advances in the realms of synthetics and medicine. Where my sister's passion was in genetics, mine rested in chemistry.

My reminiscing came to a stop as I entered my room and went to my closet to change into my workout clothes. Once changed, I tossed my work outfit into the laundry basket and stepped out of the closet. I then went to my bedside table and grabbed a hair band and briskly did up my hair up into a bun, keeping it out of my way. I walked out of my bedroom across the hall into my personal gym.

I gazed around for a moment, noticing all the weights, treadmill and obstacle course as I thought about which one I was most in the mood for. After a brief moment of indecision I got onto the treadmill and started with a brisk walk to warm my muscles up.

I had always loved working out; it provided me with an outlet of sorts. When working out I didn't need to think about anything else. I could lose myself in the challenge, the effort and the burn. I also firmly believed it helped to keep my mind sharp and alert.

A half-hour passed, after which Kai entered without knocking. He was carrying a covered tray.

"I had Anna's meal delivered as you requested. Kristoff brought it to her and will make sure that she eats it."

"Thank you, Kai." I replied, panting a little as I stepped off my treadmill and started pacing to calm my heartrate.

"Also, Gaston has arrived, Ma'am. He waits in the gym for when you finish your meal," Kai added grudgingly. I knew he disliked Gaston, but that would not stop him from preforming his duties, which, in this case, was to inform me of my guest.

I nodded in acknowledgement and sat down at the small table off to the side. "I will eat here, Kai."

"Very good, Ma'am," was his polite reply, though his smile was genuine. He always seemed to find joy in taking care of Anna and me. I never really understood how he found such joy in serving us until one evening when I decided to cook for Anna when she was sick. I remember carrying it all in just like Kai—I had dressed up like one of our maids just to make her laugh and served her in her bed. Kai arrived about an hour later with her normal dinner only to find she had already eaten. The joy I had felt in serving her, in doing something for my little sister was, to me, almost infectious. It started with serving her dinner, and then I started doing lots of small things for her. After talking to Kai about his normal duties in regards to Anna, I convinced him—and I must admit that it took some work—to let me handle some of the tasks he normally carried out for Anna.

I made breakfast for Anna every morning now. I was always up hours before she was, usually before the sun was up, and I would make her meal. Kai would then deliver it to my sister when she awoke, at which point I usually left for work. I also did her laundry twice a week.

Anna never knew about these acts of service, but I liked it that way. I did it because I loved her, not because I expected some sort of recognition from her.

Once my meal was set up on the table, Kai vanished back through the door, off to perform other duties around the estate. The plate in front of me held a steak dinner that would make any five-star restaurant jealous. The aroma was absolutely heavenly, and my stomach responded in kind.

As I ate, I thought of what Gaston might teach me today. He had been training me in the martial arts for almost six years now—well before the deaths of my parents, though it was only in the last three years that I threw myself into the training with enthusiasm. I refused to be like my parents, unable to defend themselves in the face of someone with a weapon.

Anna had been taught how to fight as well; but for much longer than me, almost since she could walk. However, unlike me, she stopped three years ago with the deaths of our parents. I think it was because her training should've allowed her to save our parents, but she froze when our family was cornered and held at gunpoint—so did I, for that matter.

I shook my head to clear my thoughts as I finished eating and got up to go meet with Gaston, yet the thought that Anna might blame herself for our parents' deaths was hard to let go.

(Anna)

I clicked off the television in my office and pushed my empty tray away from me towards the edge of the desk. There had been another news report on a mysterious girl who was able to control and manipulate ice. She had become some kind of vigilante in Arendelle City. It seemed her most recent heroism involved saving two young girls from a fire just before the building collapsed. Before that there had been this big deal about her capturing a stream of petty criminals and drug dealers, leaving them in ice chains in front a police station. And, well honestly the list goes on. She calls herself "Ice Queen." I, personally, thought she was pretty amazing; but at the moment not even the Ice Queen could distract me from thinking about my failed experiments earlier today.

"Ugh, come on Anna, inspiration time." I muttered to myself as I sat in my office, head in my hands and elbows on my desk as I tapped my foot anxiously, all thoughts of Ice Queen leaving my mind. I had spent the past twelve hours in animal trail experiments testing all my serums on lab rats with missing limbs. I had been convinced that one of my mixtures would be the right one; the one that would provide the trait allowing the rats to regrow their missing limbs without any side effects. For the most part they were complete failures, always causing the rats' death, sometimes without any regrowth at all. Other times the rats would regrow a disfigured limb and then die. In a few cases the rodents developed completely alien traits like their fur being replaced with scales. All of these were—somewhat—encouraging, at least in the sense that it was possible to transfer traits. But it was all the wrong ones, or the traits didn't bind properly or.. all these or's and if's. I banged my head on my desk in frustration before a thought hit me.

"Perhaps I'm administering the serums improperly. Maybe a vapor would be better, instead of an injection." I said, my eyes lighting up. "Or perhaps a chemical bath of sorts; something administrable to every part of the body simultaneously."

I stood up in my excitement, rocking the desk slightly and nearly causing my empty food tray to fall to the floor, but I hardly noticed as I hurried off towards my labs once more. Kristoff had arrived a few hours before with the food and badgered me until I sat down ate. Once he was convinced I was going to eat it all he left with a friendly wave saying Kai would skin him if he didn't return to the estate soon.

Once back in my lab, I moved to put my ideas in action, selecting three of the most promising serums from earlier in the day. I started to make each into a vapor, and then a chemical bath—both would be used.

I selected six rats with missing front legs, putting them in testing boxes and set the computers to administer the chemical baths and vapors when the distillation was complete. I knew it would take a few hours for the serums to be finalized, administered and then for the rats to show any sings of change. In fact it would be long enough for me to go home and sleep and return in the morning.

"Goodbye little ones." I cooed softly to the lab rats. "By morning each of you will be whole again." I said hopefully. I knew they couldn't understand me but I always felt I owed them an explanation for what I was trying to do.

I decided to visit my spiders on the way out. They were currently my crowned jewel of achievement; twelve identical spiders which I'd created by mixing the best traits from species around the word. My "super-spiders" was what I called them privately. Arachnids, it seemed, were much more receptive to cross-genetics than more advanced animals like reptiles and mammals, but still they were my proof it was possible and I loved to visit them.

I arrived at the room in which my spiders were kept and placed my hand on the handprint pad that locked the door, once my hand was scanned I scanned my eyes in the retinal scanner above it, then entered the fifteen-digit code that finally unlocked the door.

Inside the dimly lit room was a collection of clear heavy-duty plastic box habitats of my own design to provide the spiders with as comfortable a living space as possible. I even had a setup so that live food would move through their habitats for the hunt, like in nature.

"Good evening, Stella," I said to the first spider, which was currently cocooning a fly that got stuck in its web. Then I started moving down the line greeting each one. "Sabrina, Sage, Sally, Samara, Sandra, Samantha, Salena, Sandy, Silvana, Syliva." I greeted each in turn until I reached the last box.

"Sapphire?" I said in confusion, trying to locate the last spider in the line, but after several minutes of studying the box I was unable to find her. "What in the world…" I whispered worriedly before I finally located her in the back corner of the box under a leaf and I let out a tense sigh. "You worried me for a bit there, Sapphire." I said, relaxing slowly. The thought of one of my spiders escaping its box was a bit scary to say the least.

As I turned to leave there was a sudden violent shudder that rocked the whole building, it caused me to stumble and fall to the floor. There was a second larger shake and I realized it must be an earthquake. Suddenly I heard the loud scrapping screech of twisting and tearing metal coming from behind me and I turned to watch a piece of the room's ceiling break away and fall on Sapphire's habitat, breaking it open and I watched in horror as the spider jumped out onto the floor. But another quake and a loud screech from right above me had me looking up and then immediately rolling to the side as another piece landed right where I'd been. I waited for the next shudder to rock the building, but nothing happened and I sighed in relief resting my forehead on the floor.

"Ow!" I yelled suddenly as a sharp pain shot through my spine from the back of my neck, followed suddenly by a burning fire that spread through my whole body with a speed I didn't think possible. I only dimly realized that Sapphire must have bitten me—it was one of their traits to have this paralyzing, burning venom as a weapon. I grimly accepted that I was dead, for they were the most lethal spiders on the planet. I would know, since I bred them that way.

(Elsa)

I slammed my shoulder against door to the 22nd floor of Arendelle tower. The entire floor belonged to my sister and though I had permission to enter it seemed the earthquake had somehow jammed the doors. The quake had hit almost twenty minutes before and I immediately drove to the tower in one of my personal vehicles—not the family limo—to check on Anna. The whole ride over she didn't answer her phone, and I was a frantic mess of worry. The fact that the doors to her floor were jammed took it to a whole new level.

"Think, Elsa think," I whisper-yelled to myself as I rested my head on the immovable door. A metal door was between me and my sister, how to get to her, how! Then I had it; metal became brittle, amazingly brittle when super cooled. It had been over a year since my chemistry experiment that went bad and should have killed me, well honestly should have frozen every drop of liquid in my body. Yet I had survived, and in surviving it seemed I had mutated in a very unique way. I was now 'cyrokinetic' as the comic books would call it. Or in other words, I could control the cold at my will.

Taking a step back, I placed both hands on the metal doors in front of me and closed my eyes calling on my new sixth sense that allowed me to feel the energy around me and I started to pull it out of the metal, my hands were touching. I heard the tell-tale sound of cracking ice as it spread itself out across the metal and I opened my eyes, still channeling my ability as the door in front of me started to pale in color then suddenly crack. I knew it must be immensely cold, dangerously so to anyone close, but thankfully I no longer felt the effects of the cold myself.

After a few seconds I slammed my fist into the metal and it shattered. Nerves abuzz, I jumped through and looked around for Anna. I couldn't see her anywhere in the main room. The main lab was a complete mess; pieces of the ceiling had broken off and fallen all over the desks of Anna's assistants, all of whom went home at six each day, so I didn't have to worry about them being trapped in the rubble. Most of the lights on the floor were out but a few still flickered brightly enough for me to navigate and search for my sister.

Once I was sure Anna was not in the main work area, I went straight to her office, which was empty but just as big a mess as the main place. Most of the lights in the ceiling had either shattered in place or fallen to the ground in pieces.

"Anna!" I called out as I came back out of the office and started searching some of the other rooms, each one just as devoid of Anna as the previous until there was only one left.

"Of course, of course," I said to myself as I stood in front of the door to Anna's spider habitats. I went through the process of opening the door, though it seemed—like the previous security door that let people into her lab—this one was jammed as well. So I performed the same trick I had on the first; sense, ice, break; in that order. Once in the room, I saw her right away and my heart jumped up into my throat.

"Anna!" I shouted as I rushed to my sister who was lying face down next to a pile of rubble that had fallen from the ceiling. "Anna, please, please be okay." I begged as I rolled her over and immediately checked for a pulse. Joy sprang through my body as I felt it. It was beating hard and fast, faster than it should be but it was there. Next I noticed how hot she was. Her whole body was feverish, red and I could feel the heat from her body on my hand a couple of inches away from her skin.

"Oh God," I whispered in a panic. I knew how much damage a fever like this could do to someone's body if it wasn't brought under control quickly. I had created numerous medical drugs to deal with intense fevers, some without any side effects at all, but I didn't have any of those with me now and fought the panic that was threatening to subvert my mind.

"I needed to cool her down, like right now." I said. Speaking allowed me to focus my thoughts. But the only way I could cool her was with my powers and I still didn't have precise control over them. Sometimes I still lost control in my training, or during my nightly patrols. I was terrified that I would hurt her if I tried.

"It's either let her die or take this chance to save her, and I know what the sister in me would do." I said, biting my lip for a moment before steeling my will and thoughts. I would save her, there was no way I could let myself fail.

I reached down and cupped her face with both of my hands then I leaned down until my forehead was against hers. I closed my eyes and focused completely on the most important person in the world to me. "I can do this Anna, you are going to be ok. You will be ok." I chanted softly as I started very carefully to draw the heat from her body. I was mindful to take only the smallest amount of energy I could manage at a time, using my physical contact with her to feel the effects of my work on her body and slowly I felt her temperature start to drop.

I didn't let myself feel the relief, not yet—I remained focused on my task and once her body heat felt normal to me, I did my best to keep it at that level. I didn't know how long I stayed there over my sister, keeping her fever under control, but eventually her body started to stabilize on its own, and I slowly withdrew my power from her until I was doing nothing to keep her temperature down.

"Anna?" I whispered softly, but still no response. Her pulse was normal and beating at a regular rate, but she was still unconscious.

I started to search her body for injuries, only to find none that I could detect. I had a heart-stopping moment when I found one of her spiders on the back of her lab coat. It had been crushed, as evidenced when I rolled her over, but I found no bite marks on her body; and, well, she was alive, so I figured there was no way she had been bitten. I was there each time she gave examples of their venom. One bite had killed an elephant in less than a minute. So just the fact she was alive was enough for me to trust she had not been subjected to such a fate.

"Hold on, Anna." I whispered again as I picked her up easily, thankful for all the weight training I did to keep my body in shape as I started to carry her out of the tower. On the way, I ran into a couple of my guards and Kai who all looked out of breath. They all stopped in shock when they saw Anna.

"Miss Arendelle! She isn't.. she," Kai said, visibly trembling as he rushed forward.

"She just seemed to be unconscious, Kai, but please prepare a medical room for her at the mansion. Set it up in her own room if possible. And make sure Pabbie is awake and awaiting us when we return." I ordered briskly, ignoring all three of the guards who offered to carry her as I headed for the stairwell.

Pabbie was our family's personal doctor. He had lived with us and took care of all of our needs. He had access to the best equipment that money could buy, and was probably paid more than any other doctor on the planet. I wasn't sure about that fact, however, since I never compared his salary to any other.

"Yes, Ma'am." Kai said, already dialing numbers on his phone as I started heading down the stairs, clutching my sister possessively in my arms as I kept my eyes fixed on her face, silently pleading for her to return to me.
