Massive oversimplication of the dragon-dream.

I was a dragon. Most notably, I was a dragon in an odd underworld, much like a particularly video-game-pristine version of up above. I had much trouble for forever not getting along with the people I was supposed to be getting along with, particularly the military authorities.

Instead of getting along, I invested time and magical energy in some very elaborate magical defenses, becoming effectively invincible. I made much trouble for people, but much of it was because of their getting in my way. I wasn't exactly an extraordinarily nice dragon, but they did refuse to leave me alone.

Things really came to a head when I kidnapped a high-up corporate person as a hostage. To protect her from being killed by the others (since they would do so to prevent me from having her), I carried three mirage-images of her upon my back, and kept the real her inside me. But the shots they fired did not even pass my perpetually on barriers, one of blades, and I flew up, getting stuck in and tearing through many electrical power lines, to find a way to escape back to the world above.

The world above was a little less crowded, but no matter how I tried, I couldn't find a mountain secluded enough that punky kid wanna-be adventurers or the like wouldn't intrude upon me. A lot of people ended up getting hurt.
