Echos in Silence

The Echos Begin

I open my eyes.
Everything is blurry. What... Where am I?
I look around. 4 others are laying around me. In a patch of... golden flowers? Confused, I sit up.
I stand on shaky legs.
I'm in some sort of cave. There's a dim light shining from somewhere above me, and the walls of the cave are stone and have writing and pictures on them. I walk closer to inspect the pictures. They are telling some sort of story.
Long age, two races ruled over the Earth
HUMANS and MONSTERS
One day, war broke out between the two races.
HUMANS, afraid of the power of the MONSTER'S magic, captured them and stripped them of all magic.
Monsters were then thrown Underground.... never to be seen again.
Now, we wait. Hoping the 6 fated ones will fall and set us free.
I was thoroughly confused. What are monsters? What are humans? I looked down at my hands and decided that I was a human. Saying I was a monster didn't feel right.
I now went back to looking at the 5 other humans laying on the ground. One had long black hair and a grey sweater and pants and shoes, as well as a weird black marking on his hand. The second child was wearing a baby blue colored sweater and jeans, as well as black boots.The third child was wearing a white and grey striped shirt and blue jeans and sneakers. This one had long brown hair tied back in a ponytail and pale skin. The fourth had medium length brown hair and yellowish skin, as well as a blue and purple sweater, blue shorts, and brown boots.
I was confused. Who were these people? Why were they here? Why was I here? As I was thinking, the one with the white and grey suit stood and looked at me. Soon, the rest stood as well, all of them looking around or rubbing their heads.
The one with the pale blue clothes looked at the one with the grey and white shirt and said, "Hayley, what the hell did the PAHK guys do? Where are we?" The white and grey shirt girl, or Hayley apparently, responded, "I don't know, Jo. Morgan? Echo? Do you guys know?"
I just stood there with a stupid and confused expression on my face. The kid with the grey and black clothes, or Morgan, looked equally confused.
"Echo? Hello? Morgan?" Jo said, waving her scarred arms around. "Who's Echo?" I asked. I covered my mouth when I heard my voice. It was glitchy and odd sounding, a few syllables cutting out completely. The pitches changed as she spoke, as did the volume.
Everyone besides the boy looked at her in shock. "Echo..." Hayley said in awe, "What's wrong with your voice?"
I was shocked and scared before I repeated, voice still as glitchy as ever, "Who is Echo?"
