Darkness Falls

-jack pov-

I caught myself staring at (y/n), the outfit really suited her, I couldn't seem to take my eyes away, but then I finally managed. I got sucked back into the conversation when I heard North say that Pitch was back. We began talking about the things he's been doing, only minor things so far, but that doesn't mean it won't lead into something bigger. As we are talking we here a ear numbing scream. I look beside me to see that (y/n) is gone. My heart begins to race. And I fly out of my chair searching the building. There is no sign of her anywhere, And that's when I hear Bunny yelling my name. I follow to where his voice is, and it leads to the cliff hanging door.

" I thought you said this door is only open when someone is guarding it!?" I yell at North. North just looks at me trying to find words to say but doesn't manage anything. I fly out the door and all the way down to where mounds of unwanted toys, Tooth comes with me to help look. We can't find her anywhere. We fly back to The north pole factory. I'm furious, and can't even manage to think straight. I shouldn't have brought her here. I should've just let her suffer through that double  date... I couldn't keep my thoughts under control. And then sandy walks up to me, holding black sand in his hands.

"Pitch" I say sternly. "lets go" I motion to the other guardians, and we take our own ways of traveling to Pitches Cave.

-your pov-

    I feel myself falling and right before I expect a smash against the ground I am gently caught by what appears to be rough black sand. I'm engulfed in a little bubble of blackness, for what seems like forever. Then the sand begins to split open and I see light that isn't much lighter than what the black sand was giving me. I hear a sickening laugh that sends the hair on the back of my neck to stand up. I see a man in a black outfit, with what looks like to be rotting skin, and bright yellow eyes. My knees began to shake.

"stupid girl, believing in the guardians... and at such a odd age, what. a. treat... for me!" the shadow man says in a sickening voice. "w-who are y-you?" i manage to say softly.

"I'm Pitch... Black" he whispers in my ear, and I can feel his hot breath on my neck.

"what do you want?" I manage to say more clearly. he appears in front of me.

"what I want, is a weakness to the guardians, and I think I just found it!" Pitch say in a voice so evil. Black sand flies from his hands and hits me in the face, finding anyway to enter my body. It seeped its way into me, through my eyes, ears and nose. The pain was unbearable and I screamed, I screamed a blood gurgling scream.  The pain went away, and the sand stopped attacking my face. My eyes slowly faded into black to where I could barely see anything, it was as almost as if I was blind. The only thing I could see what pitch, and that...that made me feel safe. Then a big crash Came into the room. I heard murmurs of voices. Then Creatures with bright red eyes started to attack me and pitch. I fought my way through them. Continually fighting, and protecting pitch from the monsters. One of the monsters pinned me too the ground and started shaking me. I felt coldness grab my face, and the blackness covering my eyes faded away slightly and I could see Jack's face Yelling at me to snap out of it. I realized what I have been doing. I was hurting the Guardians. I pushed Jack off me, and the blackness covered my vision again. I ran out of the cave, And began to run as far away as possible. A red eyed monster followed me, and I was scared. So I attacked again. Using the leftover sand from Pitch as whips. Again I was slammed against what felt like the forest floor. I saw Jack's face again, bruised this time.... from me. I could feel the darkness inside me bubbling, and I couldn't let that happen. I ran as fast as I could away from the monster that I knew was Jack. I tripped several times before I realized I must of been wearing a dress? What all have I missed? I thought to myself. I stopped to catch my breath, hanging onto a tree, I felt the snow falling on me, and the ground harden beneath me. I knew Jack was nearby. I felt the tree I was holding on to, with my hands, frantically searching for something sharp. I felt a icicle, and broke it off the tree. I took it and forcefully dragged it across my arm. I could feel the darkness pouring out of me slowly, my vision came back to me, and I could see Jack running up to me. I didn't want to Hurt anyone, and I could still feel the darkness inside. So I took the icicle and stabbed it into my stomach. Falling to the ground, Jack held me in his arms.

"why would you do this to yourself? we could of found another way!" He screamed while holding me. I saw the rest of the guardians run up to us.

"He's gone!" bunny yelled excitedly before realizing my current situation. My eyes were fully clear now and I saw Jack's face looking down at mine before my vision went black again... But then, the moon grew as if it was running towards me. Then... it spoke. The man in the moon spoke to me. And what he said, was unreal. "(y/n), you have sacrificed yourself, for others, but not just anyone, you sacrificed yourself for the guardians. Which makes you a Guardian yourself. You have strength and courage, and a fire passion in you that can make you fight through anything for the safety of others. You are now a Guardian." The moon then began to go back to its original place in the sky.
