In the world of Terrariel, dragons have long become creatures of distant legend. However, the ancient evil did not sleep, but was ready to move in the shadows, trying to tear apart the barrier connecting the human kingdom Erathia and the source of magic, "Source", and let chaos return to the earth.
Ella, an ordinary girl who grew up in a border town, has an ancient power from the last dragon clan sleeping in her body that even she doesn't know about. When darkness falls again and her hometown is destroyed, she is forced to embark on a journey of escape and pursuit of the truth. Accompanying her are a wandering knight with an ancient oath, a young mage who is curious about magic but is cursed by it, and a dwarf engineer from the underground who holds lost knowledge.
They will travel through a vast and dangerous world, from the deep ancient forest to the magnificent dwarf capital, from the bustling human capital to the desolate dragon burial ground. Ella must learn to control the increasingly powerful dragonborn power in her body and uncover the shocking secrets about her bloodline, the disappearance of the dragons, and the origin of evil forces. The fate of the world depends on whether a girl can accept her dragonborn heart and become the prophesied "Watcher of the End."
