One day, the purple dragon named Spyro, realized that dragons were too dangerous and "ancient" looking. So he decided to do something about it.
What is that!?
As night falls, the dragons fall asleep. Spyro knew this was the perfect time to make his changes, since the humans were asleep too. He created a thunderstorm and struck the dragons with lighting, causing major changes to the dragons appearance.
The storm ended in early morning, and the dragons could no longer stay in the sky. They became wingless, and lost all their limbs, and some even developed new features. They fell out of the sky and slithered along the grass, making their way into town.
Everyone knew about the dragons in the sky and how they were dangerous. This morning everyone wakes up to realize that the dragons are gone, and these new creatures have arrived, seemingly most of them being harmless.
The king was notified of these new creatures. He found one along the walls of his castle and saw that they're harmless. He took one inside and showed his wife. He knew these creatures came from the dragons, and since the dragons used to be harmless and these creatures weren't, he was thankful for the new, less dangerous creatures.
Its okay little guy..
The king and the queen both liked how docile these new creatures were, so they decided to keep them for themselves, as something to show their royalty. The king decided to name these wonderful creatures... snakes. As he discovers more and more species of snakes, some are still mean, but most (the ones he chooses to keep) are a nice, friendly piece of royalty.
