The series is set in a fantasy world on the continent of Xadia, which is rich in magic derived from six primal sources: the Sun, the Moon, the Stars, the Earth, the Sky, and the Ocean. Centuries ago, the dragons, elves, and humans of Xadia lived in peace. However, the humans, being unable to utilize magic naturally, began to use dark magic, which is fueled by the life essence of magical creatures.[6] As a consequence, they were driven away to the west, and the continent was split in two by a massive river of lava.

1,000 years later, the human King Harrow of Katolis and his advisor, the dark mage Viren, have killed the dragon king, Avizandum, and supposedly destroyed his heir's egg. In retaliation, elf assassins attempt to kill Harrow and his son, Ezran. Ezran, his half-brother Callum, and the young elf assassin Rayla discover that the egg was not destroyed; they undertake a dangerous mission to return the egg to Xadia. Viren seizes power after Harrow's assassination and sends his children Claudia and Soren to kill the princes and recover the egg. At the end of the first season, the egg hatches into the Dragon Prince, Azymondias, nicknamed Zym.

In the second season, Viren attempts to rally the other human kingdoms to war against Xadia; he also makes a secret alliance with the mysterious, imprisoned elf mage Aaravos, with whom he communicates through a magic mirror and a caterpillar-like creature. Meanwhile, Callum becomes the first human to directly access primal magic, connecting with the Sky Arcanum. By the end of Season 2, Viren is imprisoned for treason for having illicitly used Harrow's seal, and for abusing his powers of dark magic. Ezran learns of his father's death and returns to Katolis to claim the throne.

In the third season, Ezran is manipulated into abdicating the throne amid pressure for war and rejoins Callum and Rayla to return Zym to his dying mother at her home, the Storm Spire. Viren, restored to power, leads the human armies against Xadia, amassing even more dark magic with the help of Aaravos. Soren defects to resist his father's evil goals. Viren's army is defeated by the elves and their allies. Rayla throws herself and Viren from the summit of the Spire, and Callum uses Sky magic to save Rayla. Zym is returned to his mother. Claudia revives Viren using dark magic, and Aaravos's caterpillar enters metamorphosis.
