The arrow flies through the air, flying towards the unarmored area of Smaug's chest, piercing it. Smaug lets out a thunderous roar, before collapsing. The massive fire drake stares at the burning buildings around, and sees the crossbow that is causing his death. He stares at the crossbow,  before letting out one final roar of defiance. His eyes then close and he passes.

Smaug POV

"Where am I? And why is the sun so bright? Wait. Sun?"

My eyes fly open. The bright sun. If I remember correctly, I had been dying from that arrow. Instinctively, I touch my chest, and I feel no wound. But something feels off. I roll over, and stand up. Wait. Stand up? I look down to see I'm... human?! Well, mostly human. I retain my wings and claws, dragon feet and tail, as well as horns, but I'm unmistakably human. I rush over to a nearby lake. I look into the surface, and a very handsome face stares back at me.

(Wings are like this)

"I must say, this doesn't seem all that bad. The only problem. I have no treasure."

As if the universe was trying to deem everything I said incorrect, I see a sudden glow in my inner jacket pocket. By Sauron, human clothing is complicated. I finally manage to stick my slender and sharp fingers into the pocket and I pull out a large stone.

(Art not mine, as you can see in the top right corner)

"The Arkenstone!"

I carefully admire the beautiful gem. At least I have something very valuable left, and I still have some gold stuck to my jacket. Suddenly, the wind shifts and I smell many unfamiliar smells. Including... humans? Are those humans? Why do is smell snake and wolf and other animals. I growl, taking a step back. I hate to admit it, but I'm not used to this body, so I'll have to retreat. I spread my wings, and observe them for any damage. None, so I start to beat them, lifting me a few feet off the ground. I fly over the trees, but not before an arrow shoots past my head.

Soon I hear the whistling of more arrows, and so dive downwards, and about five more arrows shoot over me. I turn around and spew a blast of orange and white flame. I turn and keep flying, hearing a loud explosion shaking the trees below me. But an arrow suddenly tears through my wing. I feel like a thousand swords have pierced my skin. I roar in agony and crash into the ground. I glare back at my pursuers, watching them emerge from the brush.

"What. The. Literal. Shit."
