Long ago, in the magical land of Kumandra, dragons, creators and guardians of water, lived side by side with humans. Peaceful life came to an end when the Druuns appeared. The creatures of darkness turned people and dragons into stone sculptures, and only the magic of the dragoness Sisu was able to drive away the evil creatures and split people, but it had no effect on the dragons. Kumandra split into the states of Heart, Fang, Claw, Ridge and Tail, and the magic dragonstone was kept in the Heart country, ruled by Raya's father. He dreamed of uniting the lands, but human greed and envy caused the artifact to split. The ruler of each country got a shard of it, and the Druuns once again ruled undivided.
A few years later, Raya and her faithful companion Tuk-Tuk fearlessly travel across the scorched desert, exploring the remaining rivers and never giving up hope of finding the last dragon - the last hope of humans to defeat the Druuns.
