The Lost Demon

The Past

...it was my grandpa!!!!
"Grandpa your still alive? "I ask.
"Errr..ummm. sure?" He responds.
"Wake up dude, I think he's dead! Or maybe im stupid" it was a familiar voice, it was Jahir.
Open my eyes
"Ahh, my head, it's thumping so hard!" I say.
"Relax, we have a big day ahead of us," David says.
I hop onto his boney back and we fly towards an area I have not seen yet.
"This is the training camp, where most dragons come to train. Only newborn dragons and recovering dragons are allowed to train here. But since you're here, we must show you our skills," David says to me.
Then David popped his knuckle bones out and stabbed the nearest human dummie. He also spun around and his tail hit the dummie covering it with sharp bones. Next the ice dragon, Japheth, grew icicles on every part of his body, then they went flying, hitting the dummie and us too. He could grow enormous icicles and use them as melee wepons. He also froze the dummie and made it shatter into a million pieces. Then there was Jahir, he was a fire dragon. He could breathe fire and was able to make temperary fire minions who attacked the dummie and slowly disintegrated. Last but not least, there was Jared, an earth dragon. He was capable of tearing apart buildings and smash it into dummies. He could take a huge chunk of dirt and fling it onto the dummie! And the coolest ability he had was make a structure out of anything he could use, for example he made an eiffle tower out of rocks!
"There it is kid, like what you see?" David asked me.
"Hell yeah!! The most amazing shit I've seen in my whole life!" I say amazed at what I saw.
"Well we better head to your realm, before your parents start wondering where the fuck you went." David says
"Yeah...umm, you guys kinda destro.. Umm they don't care for me anyways!" I angrily shout.
"Ohh.... chill buddy, you've got us and that's all you need right?" Jahir interupted.
"Yeah sure, but where already your guys' parents?" I question.
"Well champ, you see once our dragon parents mate and lay eggs they stay with the young until they are old enough to fight. You see here it is very tough to be a dragon because there can only be one child. So we fight to the death, while we are young to find out who is the strongest. Then our parents leave to war and we stay to continue their legacy." David explained
"

woooooooooow! That's pretty rough man, is that how... so your telling me... I have sooo many questions!" I confusingly say.
"Yeah that's just how it works, but some dragons get lucky and their siblings either don't hatch or they're one of a kind like me!" He proudly says.
"What do you mean by that? Like... so you were the only one who was born?" I questioned him.
"Not exactly, when a dragon egg is rare, epic, or legendary it is law to make sure it does not get killed. Even if they're weak! My father was an earth dragon and my mother was an epic fire, bone breed. Meaning she was an epic dragon, however there was only a 5 percent chance of breeding her bone characteristic. But lucky me, my siblings were all fire common dragons, I never met them because I was taken by..." He suddenly stopped. I knew I shouldn't talk because every other dragon  walked away, and so did I. But the thought was still running through my head, who could've taken him?
"Let's head back home." Japheth suggested. So I hopped on David's back and we left. I felt bad for him, but I still had a question that I did not dare to ask in that sudden moment; what war is he talking about?
