This is one i played in the old yahoo roleplay rooms, and ive just thought of it again today.
For over a thousand years, dragons where accepted by the peoples of Armengar, a land that stretched for a continent. Our wisdom was accepted by both the common folk, and nobles, as well as even royalty. We shared our wisdom, mediated in conflicts, used our magic to heal, whatever we had to.
Humans served us willingly, and repaid our help with food, service, and gold, which we hoarded. Such help would one day be our undoing. A new king in the eastern lands resented our influence and riches, and gathered an army. He managed to talk the common people and nobles into beleiving that we were a threat to humanity, and the majority joined his army.
Not everyone did, but those that didnt learned to keep their conflicting opinions to themselves, or be lynched.
His first attacks on dragons came as a surprise, we didnt beleive that humans would really attack us, yet it was confirmed later on.
Our choices were simple, kill the king and his army, or flee. The king was the ruler, and had authority. We debated what do to at a special council. Some were opting to fight this army, while others were in favor of flying to lands where no human would ever find us.
The council deliberated for over a week before the majority decided to fly to lands out of the range of man. The ones who disagreed were forbidden to fight this army, but werent ordered to leave. I was one that didnt want to leave. I was young by the standards of my race, only 500 years of age. My scales were a brilliant green, which always caught the attention of male dragons during our mating season.
I wouldnt flee, but i wouldnt kill those that i had sworn to protect. So i took human form, we could do that, a skill that only the most trusted of helpers were aware of, and travelled to the lands of the elves for sanctuary. I took with me some of my own riches, and sealed the entrance to my cave, to keep out anyone who came looking for me there would find nothing.
200 years passed, and the kings lineage continued. By the time the people learned the truth about the real reason for the kings crusade against our kind, our wealth, it was too late. His men kept order and killed any who resisted. Many wanted us back, but our caves were either empty, or sealed.
The descendants of those that supported us kept the truth alive, and hoped that dragons would return. I continued to live with the elves, with my new cave, and a waterfall to bathe in. I kept to the company of elves who came to visit, and worried about the people that i once cared about.
If this one appeals to you, you could play a warrior, who heard rumors that one dragon refused to leave, and lives on elvish lands,to find me and request my help. male or female, either is ok. Or maybe a mage, male or female, who seeks me out.
The elves wouldnt let humans in, so you woudl have to infiltrate elvish lands to get to me, and even then, you would have no way to tell if i would help you, after all, many dragons were killed by the advancing army, and we have long memories.
