This was just a random idea I had one day.

It has been 1000 years since dragon shifters took over the world. The humans are forced to serve under them, whether they be slaves or just servants. The dragon shifters are now the dominant species of the planet. They are powerful and strong, almost impossible to defeat, or so many humans thought for years. The dragons make the humans do all the work that they themselves do not desire to do. Humans cook for them, clean for them, grow their food, take care of the farms and livestock, entertain them, as well as many other chores that one can think of.

The humans had fought back during that struggle 1000 years ago, but sadly the humans lost the fight to due their lesser numbers. They soon lost hope as the years passed, fearing that this was life now, the way humans were to live for the rest of eternity even if they did manage to fight back. They felt helpless. All hope was gone in their eyes. There was nothing to do that could help them, or so they believed.

The dragon shifters believed they would rule forever. They assumed the humans would never fight back. They scoffed at the idea of the humans regaining any hope in regaining their world, their freedom. They had won that struggle 1000 years ago and they do not intend to loose what they have taken from the humans. The dragon shifters would make sure the humans served them for the millennia to come, and then some. The dragon shifters thought little of the humans, whom they considered a worthless species.

However, there was a prophecy, one the humans had long forgotten about. One day, a hero would emerge, with a power that could defeat the dragon shifters and free their world. This hero would banish the dragon shifters once and for all and the humans would have their world and their freedom back.

One night, under a full moon, when the wolves all howled at once, that was when the hero would arrive and the prophecy would begin...
