Long ago in a lost kingdom there was a dragon and an elf. The dragons and elves lived together in harmony with each other for thousands of years until one day a rogue elf decided to go on a killing spree and killed almost every dragon in the land. Only two dragons remained and they took drastic measures to keep themselves hidden from this rogue elf. So, they have been in hiding ever since but they had another secret to keep the dragons from going extinct they consulted a witch and she suggested that she could cast a spell that made their child half human half dragon so they could keep her hidden. They reluctantly agreed and said do what you must witch. So, the witch granted them with the child but she left a few details out. The dragons would turn to stone for 1,000 years and the only one who was left was the child.
The elves stayed up to date with the world and went into hiding because as the world was growing older humans started to fear the unknown seeing as they knew the histories between the elves and dragons but had no idea of the elves or the dragons powers. They were especially cautious of the elves because of the rogue elf and of course all elves are not the same but they didn't want to risk humanity being slaughtered. That is all we know on the elves and dragons history.
