The Elements.

[Halla's POV]
I was chained up to a thick brick wall. My blistered hands were taped together, I was drained and I couldn't unleash my power. I figured if I could slide my legs to the ground, it would activate some sort of frost. I looked to my left, I saw my own sister torturing Yoongi. He wasn't showing any sort of emotion, blood was all over his face and I started to panic as Tiffany blistered him. I cried out, "Stop torturing him, you bastard!" I heard her smirk, "Shut it, Halla. Or you'll be next. Looks like Baekhyun is battling Hoseok, Taehyung is down, and Jin only has his blood-suckers. Also Jimin was killed by Minah. How does it make you feel, baby sister?" I knew she was taunting me. My pupils were dilating and I could feel my body tightening. I was going into panic..
I kept shouting.

My eyes then opened again and I was back in my room, I was drenched in sweat and Taehyung and Jungkook were sitting across from me with wide eyes. "What the hell happened to you?" Jungkook asked. "I had a nightmare.. that's all." I muttered. "Halla, that was worse than a nightmare.. your eyes are blue and you're shaking. Your pupils are huge.."
Taehyung said as he grabbed my hand. "Yoongi was being tortured, you were down by some villain, Hoseok was battling Baekhyun, my sister was the one doing all these things.. she's some sort of commander. It felt so real.. The only ones that were stable was Jungkook, Jin and Namjoon. Jimin also died..." I shook out.

"Halla.. it's going to be okay. Nothing like that is going to happen, and if you felt like this was supposed to happen, you need to go talk to Jin about it, he's the only one that can see into us." Taehyung spoke. I nodded, "I wanna do it alone, I'll meet you both later.." I said. I went into the bathroom and changed out of my pajamas. I slipped on a white t-shirt, leather jacket and some leggings.
I transported into Jin's library.
"Jin?" I asked. "Yes?" He turned around in his chair. "I had a nightmare last night, and I need you to help me clarify something." I stated. "Which would be?" He asked. My eyes were shaking, my vision was blurry.
I started to tell him everything, he put his forefinger to my temple. His eyes changed to a dark red. He was definitely seeing something.

I timed him, it's been 3 minutes.
"Jin.." I whispered.

His eyes returned to normal..

[Jin's POV]
I saw every. single. detail. that she saw. Her sister is alive, but I can't tell her that. It'd make her go look for her and put her in danger. The Calvary knows Tiffany and Halla are related, they have Tiffany in their HQ, she's some sort of manager there, she has Sonic scream. Screams like those are ones that can send you through a wall and so on, if she's strong, she can really kill one of us. One of the members turned her into a vampire, so she's now immortal, unless someone sticks a dagger in her heart.
This is to only protect her.

"It.. was just a dream. You imagined it." I said. I couldn't imagine any of that being real, but my gut is telling me some sort of event will happen like this.
"Okay, thanks Jin." She smiled and walked out.
I sighed..
I'm sorry, Halla.

[Halla's POV]
I decided to go out for a while. I needed some fresh air and I decided to take Jimin with me. We walked through the woods to a river. It was frozen since it was winter. I sat on the snow and looked into the river.
"Can I ask you something?" Jimin asked. I nodded, "Yea, what?"
"What would you do if I died?" His eyes were grey. I stared at him for a second, "I wouldn't forgive myself if I happened to witness it and couldn't do anything about it, I'd be very upset, depressed even. That goes for any of you." I said.
"Interesting." He mumbled. "What do you me-" I stopped when I saw Hyuna in the distance, she was staring directly at me. Her eyes were also grey, like Jimins. He was being mind controlled, this wasn't him.
I got up and darted back home. Hyuna eventually caught up with me and grabbed my legs back. I was then on the ground being dragged. I screamed as loud as I could. "Hoseok!!! Taehyung!!" I yelled. I was being pulled out into the snow. It was cold, but it wasn't bothersome. That was until she threw me into the freezing cold river. She stepped a hole into the ice, I was trapped in the hole. I banged on the ice block. I was losing my oxygen.
I heard a loud thud and pop from above. I tried to get my dragon to activate from underwater. I focused for a bit and I spun my fingers until it came up from the ground. It smashed into the ice, creating an escape hole. I crawled out and saw Taehyung fighting Jimin. Hoseok was fighting Hyuna. I coughed up the freezing cold water and shivered. I got up and I suddenly felt something puncture my legs, it was stinging. Hyuna hit me with one of her fire bolts. I shot back at her with an ice bolt, it scraped across her jaw, splitting it open.
I felt a pair of arms wrap around my waist, it was Taehyung. I breathed out, "Are you okay?" I asked. "I should be asking you that.." He said as he picked me up and grabbed Hoseok as he finished Hyuna off, she was being suffocated, Hoseok made her suffer, I looked away. "Don't you dare touch her again, next time I'll murder you. Get off our land, or I'll choke you way worse than I just did." His voice got dark.
Taehyung didn't bother with Jimin, he eventually snapped out of it. It wasn't his fault, but I knew something was wrong with his question.
"We both heard you screaming, we tracked your voice." Hoseok said.
"Thanks for saving me." I said as I leaped out of Taehyung's arms. I wrapped my arm around Tae's back. "Wait. Taehyung, you're bleeding.." I said as I wiped it from his forehead. "I'm fine, babe. You're the one that needs attention." He said.

It's been 6 hours since the incident. I felt like shit. I couldn't warm myself up anymore because of my powers. I walked into Taehyung's room and I laid down on him. "You're cold, aren't you?" He asked. "Yes." I muttered. His hands went up to my arms, he didn't use his powers but he radiated heat to me. I slept with him until I could get up in the morning.
How many people can say they have a boyfriend that can literally warm them up?
I eventually fell asleep on his chest.

[Time skip: 8 AM]
[Halla's POV]
I woke up and silently got off Taehyung's chest, I threw on a flannel and scarf and some boots and walked into the woods again. I was fully aware of what I was getting myself into. But there was a gut feeling that my sister is out here, somewhere.
I heard a shift somewhere in the distance. I ran towards it. The figure was my height. I stepped on a stick, it snapped. She turned around. It was her...

"T-Tiffany?" I breathed out, my eyes were watering. "Oh my god.." She mumbled. "Why didn't you ever come home! I had to live months and years without you! I needed advice, that YOU were supposed to give me. When I had girl problems, I always had to go to mom, because I thought you were dead somewhere!" I screamed at her. "I'm sorry, it wasn't my choice to leave you and our parents." "Who the hell took you!?" I yelled. "I can't tell you that, but I'm still hoping we can catch up.." She said calmly. How the hell can she be so calm? "How can you be so calm! It's like you don't care that you've seen me!" I cried out. "I have seen you.. multiple times. But I was in a disguise. I saw you go to a different school, I saw you walking to your old high school the day YOU went missing. I've known, and I would've reached out, but I come back here to see how you're doing. I know you have powers, you can't tell anyone, but you really are strong, you can take the whole Calvary out if you wanted to.." She stated. I ran into her arms. I felt her arms go around me. "I'm so sorry." She mumbled. I felt her figure linger away. She disappeared.

I sighed.
Then who the hell keeps up with her...

Notes

So, she saw her sister in the dream and the woods.... rut-roh. ;) You guys are so gonna hate me in the future the way this story twists up. Lmao. But I will let you guys know that I am going to be writing a BTS Vampire AU after I finish this. So.. woo hoo!
But the death's that Halla saw in her dreams aren't real. It'll be worse. If you guys watch Pretty Little Liars and saw how the girls were trapped in the doll house/vault it's going to escalate like that soon. But we have plenty of chapters to go til that. You won't expect it. ;)
