What am I?

The Savers

"Is this a joke to you, just tell me are you the keeper I have to destroy? Are you normal?"
With the look of horror I couldn't help but scream.
As Shawn grow bigger everyone ran inside the house all except for Tacia, Tod and myself.

Tacia through down her drink and started to grow as well. While I was frozen with fear Tacia took on Shawn. With a fist towards his face, Shawn ducked and tackled Tacia to the ground.

"Come on we have to get out of here, can you move your legs Bella?"
"Oh yes but what about Tacia?"
"Tacia can handle him we have to get you to a safe place."
"No Tod I can't leave Tacia..."
"Tacia is fine. I'll come back to help her, we need to get you to a safe place."
And with that said Tod grabbed me and teleported us to what looked like a panic room.

4 hours had past and I was still in the weired room with no one but myself. A bright light caught my eye and as I turned around I saw Tod holding Tacia in his arms.
"Is she okay?"
"Yes she is, she just needs to rest."
"How did Shawn do that, how did he grow and turn into that hideous beast?"
"He must've been a hunter."
"A hunter, what do you mean by a hunter?"
"I mean he was not a human being he was a monster out to get..... YOU."
"Me? Why me?"
"Because you are the last piece of the puzzle."
"And that means?"
"That means with Tacia's size, my knowledge and your power we can create our home planet again."
At that point I was so tired I didn't have much of a reaction.
"Well it's late you better go sleep."
"What about my parents?"
Yea sure they weren't my real parents but I still cared a lot about them.
"They will be fine, Trust me."
"Okay, I trust you."
