Quest for the Dragon's Gem

As a baby, a young girl named Andra has been cared for by a family of dragons in the mountains. But many had believed it was a made-up rumor. That is until one day, King Arthur and his Knights of the Round Table has been foretold that a young warrior who's not what she first appeared had somehow found the legendary and once-lost Dragon's Gem. They had to get to the girl first before Ruber finds out about her. But that's when King Arthur had disappeared without a trace, but a dragon had appeared and started terrorizing the kingdom.

(Don't worry, I'm writing for fun. Also, the dragons looks like the ones from Lego Elves).
