How to Train your Dragon, the Night Furies side

My name wasn't always Toothless. I was once known as Night. I had it all, two sisters, one was a twin though, a crush, a home, everything a Night Fury ever wanted. Until my Uncle found me and chased us out and killed my parents. After that he won't stop going after me. He kills my father first, then my mother, then my sisters! When he kills my mate and takes my eggs, I lose it. I save one egg while the rest, fell to their fate of never seeing their first day. He becomes too much of a nusence and I must run him out somehow. But the question is. How?
