Our Never Ending Adventure

This is my first fanfiction. So if you think it sucked, turn away. But if you are interested, go ahead.

A long time ago, mystical creatures such as dragons and unicorns were believed to exist on earth.
Although many believed that the mystical creatures were already instinct, very few doubt that they are gone. Humans also follow the old ways as kings and queens ruled the kingdoms across the land. There are many kingdoms on earth, practically thousands. However, one kingdom stood out the most, as the wealthiest kingdom of all.
The kingdom of Fiore.
In that kingdom, there lived a princess. The princess is the king and queen's proud and joy as well as the kingdom's. The beauty of the princess was spread far and wide all over the land. She was by far the prettiest maidens in the kingdom and the fairest among all princesses. Many suitors and princes came over to ask for the princess's hand in marriage, but neither had succeeded.
Now, this story is all about the princess, who found one of the so-called mystical creatures. In some way. A very peculiar, and rare creature.
A dragon.
How did it happened? Read on, and you'll know how their adventure starts.
