How to train a dragon

       Once upon a time, there were dragons who roamed the world(I define the world as the universe). There were two kinds of dragons, which were Western species and Eastern species. The two breeds were very different from each other. Eastern dragons were kind, protective to people, and respected by gods. On the other hand, western dragons were violent, cruel, and evil. Also, there were two tribes who lived among the dragons. The Viking tribe, and the Draco tribe. The Viking tribe hated dragons, so they didn't raise ant dragons. So, they had to build an army completely comprised of people. However, the Draco tribe lived harmoneously with dragons. They raised dragons, and they could have a strong army comprised of both dragons and people who were trained specially to battle by using dragons. In fact, the tribe had the strongest army in the whole world! Since now you readers know the background, I shall begin the story.
       One day, the two tribes had a big fight over who should harvest the moon-corn which have grown on their border. The fight got bigger and bigger. Eventually, the fight became a war. At the beginning, the Viking tribe was winning because without dragons, Draco tribe was weak. You might ask where the dragons are. Well they were taking a wonderful break after lunch. Then eventually, they heard the swords clanging, screams of people being slayed, and everything. Soon, the dragons were up on the battlefield, helping the Draco tribe. Western dragons and Eastern dragons worked with each other quite well under people's supervision, considering Western dragons fight with Eastern dragons often. When the war ended with the Draco tribe winning, Draco tribe had a feast. Eastern dragons participated in the party, but Western dragons were hungry for some more war. So, they started to tick off the Eastern dragons. Although Eastern dragons are tolerate, they got really annoyed and started to fight the Western dragons. The Draco tribe panicked and ran away from the scene. Even though the tribe stayed far away from the dragons, they could hear the loud roaring, fire being breathed out, and Eastern dragons' nonstopping negotiation. The dragons from far away started to watch the war or participate in it. The war was unstoppable for the puny people.
       The war ended twenty years later with the Western dragons' defeat. The Eastern dragons were practically weaker, but the fear of disaster for people led to less number of Western dragons. So, basically Eastern dragons won by having an advantage of the number of the participants. Anyway, the village was destroyed. Burned houses were left open for theft. The crops were gone. The water evaporated from the rich lake. The Draco tribe just could not establish a new tow there, so they deserted the land. After fourty years of searching, they are said to be living in a planet called earth. And as the decendants of the Draco tribe, dragons are alive and kicking in our minds. I cannot stop but wonder, was living harmoneously with dragons really a benefit for the Draco people?
