Shin-ha's twin sister? (Yona of the Dawn) (ABANDONED)

Hidden Power?

My name is Moon and I am The Blue Dragon Warrior's sister. I call him brother because he does not have a name. The villagers refused to give him a name. I have the same light blue hair, well we are twins, I also ware the same type of clothes as he does for three reasons. One it's easy to fight in, two so the villagers can know that I'm the blue dragon's sister, three so I won't forget who me and my brother are. The first time I saw him sense birth was when we where moving to a new location for the village. Once we had gotten to the new location which was in a mountain, the village sucluded blue dragon and they put up a secret entrance also a secret passage so he would stay sucluded from the village. The only one who would go and just talk to him was me. I knew his eyes could kill people if he willed them to or if he lost control over them, but I wasn't worried he's my only real family. It's been 12 years sence we came here and blue dragon has been in that cave alone. I didn't want to show my power but I also didn't want him to be alone with Ao, that's his squirrel he found 12 years ago, so I decided to do something crazy. I went out side to catch the cool night air and went back inside the mountain. I knew fresh air after a long time would make my power go haywire so I headed to the entrance of brothers cave. When I was outside of it I opened the door and that's when I felt my power go completely haywire. I started to change into a dragon that was dark blue, the spikes and the horns was the same color as my hair *see picture*. My tail reached the entrance and my snout was a little ways into brother's cave.
"Darn it. I didn't expect I was this long and big." I snorted. I was stuck in in the passageway the only way to get unstuck was to change back.
"It's a monster." I heard the villagers fearful and anger yells. I smirked and blew a bit of fire down into brother's cave. He came up to see me start to change back to my original form.
"That's better." I said stretching as I did that my back popped. The villagers had fallowed my tail as it retreated, it had lead them to me.
"Your that monster Moon?" A villager asked.
"It wasn't a monster it was a dragon and yes that was me." I said turning around. When I did that the villagers backed away in fear. I smiled to reveal sharp k9 teeth.
"I am the blue dragon's sister what did you expect, me not to have some sort of dragon abilities?" I laughed. They where speechless as I stood there smirking. I was fading fast with how much energy I used in that small of space. My vision suddenly went blank and I started to fall, and I saw my brother rush out of the darkness.

Blue Dragon P.o.v

My sister was blacking out. As she fell I rushed out of my cave to catch her before she hit the ground.
"It's him it's blue dragon." I look up at the villagers who where far away from me and my twin sister. Even though I had my mask on they still backed away more.
"Take your sister down there with you we don't want to see ether of you." An elder said pointing to the cave I came out of. I stood up holding her bride style, no one could tell but I was glaring at them. I turned around and headed back down into my cave with out saying a word. Why would you choose to live in the darkness with out seeing daylight? I wondered as I laid Moon in a cave that was close to mine. I lit it up with torches so she could see and find my 'room' as she has called it. I hurried out after I put my fur head piece over her. I sat in the lonely darkness of my 'room' playing with Ao waiting to ask Moon why she did what she did.
