Hundreds of years ago, you and Nikolai were lovers. The both of you were supposed to kill Tezia. A showdow from the depts of hell itself. It can morph into any person or thing. But when it's in its regular form, it's huge. With thick black claws. Its teath so sharp it could stab a boulder in half. It only had one weakness. Enchanted blue or black metal. There were only a few rocks left in the world with this. Including both of yours and Nikolais swords. You had yo kill people to get where you were. You didn't know how much that would actually cost you...
You had a huge fight with Tezia. You stabed his eye out of his socket. Tezia slashed Nikolais arm deep enough to see the bone. Tezia tackled you to the floor and digged his claws into your rib cage. You made a horrible scream. Nikolai weakly threw his sowrd at Tezia. Tezias screamed and tried to pick out the sword, but it was no use. Your clothes were stained with blood. You dragged your sword to Tezia and cut his head off. You used your powers and trapped him in a rock. He could only be set free if the rock was broken.
But what you didn't know is that you were giving a second chance. You only got to Nikolais one last time. He kissed your forehead and spoke gently in your ear.
"Find me, my dear.."
Then whiteness... An angle went behind you so you couldn't see them. He placed his fingers on your shoulders. He told you that you were supposed to be punished for your murders. But that Nikolais had truned the punishment to himself. You both were to go back to earth as babies. You just thought that means you could fined Nikolais in the other life. But the thing is he got his memory erased.
16 years later
Earth, it was a lot different. There was technology and whatnot. It was your first day in a new school. The teacher showed you around, then you saw him...Nikolais the both of you were paired up for a field trip but you got lost following a girl who had dropped a rock. Smoke forced its way in her mouth took you a second. Then you knew what it was.
