Time skip at the beginning here, I'll try and explain everything that happened, just try and bear with me.
Hiccups word is Thing.
This chapter also has a bit of blood, I'll try not to go into the gory details, but be warned.
Crap, I have no idea how to start this. Well, here goes nothing.

Hiccup

Ahh, I love the feeling of a nice cool breeze on a hot day as I lay in the peace and quiet of my desert.
As usual, that was about the time the screaming started.
I jumped up immediately and started running towards the sound, it was coming from the small thicket of trees by the old building.
As I ran I concentrated harder on the screams, it was coming from multiple people, that was for sure, and there was at least one female, or a man who screamed like a girl, but the former was more likely.
As soon as I reached the first trees I hit something soft. I heard a girlish yelp, possibly my own, and hit the ground. As soon as my head cleared up some, I jumped up again and looked at what I'd hit. It was a girl, about a foot shorter than me, with short brown, more chocolate coloured than my own, and a face of pure terror.
"Are you ok?" I asked.
"I-I think so, but Merida, and the others, they're still back there!" She pointed back to where the amount of screams had dramatically decreased.
I nodded and started running in that direction, surprisingly, the girl followed.
It seemed to take an age to reach the small clearing, and by the time we did, there were no screams left.

(A/N did I just kill Merida? Am I really that cruel? I didn't know I had that in me!)

The clearing was strewn with bodies, both human and Things. Judging by the girl's face, she'd never seen this kind of bloodshed, I mean, I've seen this kind of bloodshed before, and I felt like throwing up, too.
Despite being about to up chuck her lunch, the girl still forced herself to look at each of the bodies. I assumed she was grieving or something so I remained quiet.
Then, after a few minutes, I decided to break the silence, "I'm so-"
"Merida's not here." She interrupted.

(A/N I guess I'm not that cruel, huh.)

"What?"
"Merida, she's not here, and all the arrows that killed those Aliens, they're hers. I think she went that way." She pointed across the clearing and started walking that way.
"Wait, what?" I was still just standing there, stunned. Could her friend have survived?
The girl kept walking. Seeing no other choice but to follow her, I ran to catch up.
We walked for a little while in silence until she put her hand out to stop me, pointing at something on the ground, I didn't see anything but whatever she did see (whether or not its actually there, I thought) made her run with renewed energy.
We had almost made it to the tree line when a voice came out of seemingly nowhere.
"Don't move a muscle or, I swear, I will shoot this arrow into your eye socket."
"Merida?!" The brunette girl called.
There was a short silence before, "Rapunzel?"
"Your alive! I was so worried!" The girl, I now assumed her name to be Rapunzel, squealed.
Another girl, this one with a bushel of bright orange hair, dropped out of a tree to my right, and the two girls embraced.
"I thought a Hill Crawler like you would be dead in 10 seconds flat in a fight like that." 'Merida' laughed, but discretely wiped a tear from her eye.
"I still don't know what a Hill Crawler is." Rapunzel laughed back.
I awkwardly cleared my throat, not wanting to ruin the touching moment but not wanting to be ignored either.
"Sorry, I'm being rude." Rapunzel said, "Merida, this is... I don't think I caught your name, actually."
"Hiccup," I said.
"Hiccup." She repeated, "I'm Rapunzel, and this is Merida. Thank you for helping us."
"I didn't really do anything." I muttered.
"Nonsense!" Rapunzel argued, "You helped me get the courage to come back! I'd never have found Merida again if it weren't for you!"
"Yeah," Merida agreed, "we at least owe you dinner! Lemme just get our supplies!"
"I'll come!" Rapunzel offered.
"Yeah, me too!" I honestly just didn't want to be left alone.
So we all trekked back to the battlefield. I realised that the girls only got their own rucksacks, not the ones of their dead comrades.
"Shouldn't we- er- bury them?" Rapunzel asked as she delicately stepped over a fallen Thing.
Merida looked at her blankly, "It's a harsh world. Folk don't get buried in a harsh world." She gathered the rest of her things and walked out of the clearing. Rapunzel and I hurried to follow.

"So, what happened?" I asked. We were in the old building, surrounding a fire where two skinned rabbits were roasting, when I finally broke the awkward silence. "And what are you doing in these parts anyway?"
Merida took a deep breath and began to explain their plan of activating the Genocide. But it wasn't until she mentioned that they needed 10 people that I realised why it sounded so familiar.
"You mean the Wipe-Out?" I interrupted.
"Does everyone have a new name for it?!" Rapunzel complained.
"What do you call it?" I asked, honestly interested. Like the Things, which I had already noticed that Rapunzel called Aliens and Merida called Trolls, the Wipe-Out always had a different name depending on who you spoke to.
"Well, the book I found called it the Cure." Rapunzel answered.
"Oh, like what the Guardians call it."
"Who are the Guardians?" Merida asked.
"They're a small team of grown ups that take care of a group of kids and young families. They used to live in a Haven in the mountains, but they were found. More than half their number were killed. They've been looking for a new Haven ever since. Hey, speaking of families, were you two actually going to make one with those men that were with you? They seemed kind of old!"
"What? Why would we make families with them?" Merida looked disgusted by the idea.
"Um, when you repopulated the earth?" Their faces went from shock to realisation, then Merida's turned a little green. They obviously hadn't thought about that. Of course I did though, I'm like that, and now these girls probably thought I was some kind of pervert. "If you're still planning on the Wipe-Out, though, I could recommend a place with a few very eligible young gentlemen."
Merida glared at me and Rapunzel blushed like crazy.
"I'm serious though, those Guardians I was talking about? They passed by here a couple days ago, it'll take about a day for us to catch up."
"Us?" Merida asked.
"Well, not meaning to sound arrogant or anything, but if you're wiping out the human race, I wanna be one of the ones who survive."

That was a surprisingly difficult chapter to write, I got mini writer's block every second paragraph.
Is that too sudden of an ending? I'm not sure, but I don't think I can write any more without writing a lot more.
Anyway, now we have Hiccup, I was gonna introduce Toothless too but couldn't fit him in anywhere, maybe chapter after next?
And I think everyone can guess one of our next newcomers, but can you guess the other?
