I am Eruanna, daughter of King Thranduil of the Woodland Realm and Erulise, who was Beorn's sister. Supposedly, sometime after the death of the king's first wife while he was still mourning, he and my mother met and she was just what he needed. He was allowed to wed her and eventually I followed.
I grew up in Greenwood with my half-brother, Legolas. We grew to love each other as brother and sister, though it took him a while to fully accept my mother and I. The elves didn't accept me at first either. I didn't have pure elf blood and they were skeptical of the king loving another. In time though, they accepted what had happened and showed some respect.
I was in my very early teens when I had first transformed, in the light of a full moon. My mother said it'd help until I was able to change skins on my own command, but I discovered that she said that just to make me feel better. I had transformed into a beautiful wolf with a significantly darker coat than other wolves I had seen before. I was also a considerable amount larger than the size of normal wolves, enough to make anybody do a double take, even if they had heard of me. However, I was also different than the average skin-changer.
Shortly after the revelation of my wolf skin, my mother took me to visit Uncle Beorn. During this visit was when it was discovered I had a third form. I could take the shape of a dragon.
Uncle was telling me of a legend that had been around for a long time. There was a sorcerer who had a strange fascination with dragons. He studied them and went looking for some and once he had set his eyes on one, he had a thought. He somehow managed to create a skin for himself using the blood of a dragon. He could then transform into one of these dangerous creatures. Content that he could now be what he loved so much, he returned to civilization. He found love, love for a woman that so happened to be a skin-changer herself. They wed and had a child whom the sorcerer had hoped his form would pass to. That wasn't the case though. He was thoroughly upset and that was when the mannerism of dragons started to show. He grew quite fond over precious metals which caused many a problem. It had gotten to a point where he was stealing and willing to kill, for he had a terrible and ever growing lust for treasure. His family had to constantly cover for him, but he soon realised what he had become and recognised it had to stop. He had to stop. But he knew that he could never do it alone. He informed his wife and son what must happen and though they readily agreed, they didn't want to carry through. If they wanted to prevent it from getting worse they needed to end him. And they did, but only after expressing their love to one another, one last time. Many years afterwards, his wife perished, though his son found his own love, another skin-changer. They had three children two of which were average. However, after the third child first shifted, it was soon discovered they had a third form. This was the skin that their grandfather had acquired. The gene had passed down after all, but it skipped over a number of generations before it showed up again.
After listening to him recount the story, I looked up at the stars and imagined myself as one of them navigating the vast sky. Beside me, I heard Uncle Beorn stand abruptly. It caused me to open my eyes and look at him. I quickly noticed the flabbergasted expression on his face. I opened my mouth to ask him why he wore such a look, but all that came out was a bizarre grumble.
I was certain my look matched his by then. In an instant, my mind thought back to the story he had just told me but I kept trying to convince myself it was nothing more than that, a story.
My curiosity got the better of me though, and I looked down at my body. I stared at my scale covered chest and froze in shock and astonishment. After I got over the initial shock of seeing myself in a dragon's body, I turned my head around to see spines protruding from my back. The fact I could even see down my back startled me. I then lifted my arm and gawked. It had been shaped into a wing.
When I finally regained the ability to move, I shifted my gaze back to Uncle Beorn. I decided to change back to my general form so we could communicate, however, both of us were still at a loss for words. I was the first to speak saying, "I suppose it's not just a legend, then." All he did was shake his head.
He then turned to look at the house and said, "We should go tell your mother." And so I showed her my recent discovery. We agreed that I keep this newfound discover a secret. Most see dragons as enemies and those that don't, want me on their side as a sort of weapon.
