Eight ordinary siblings stumble upon a glowing map and discover the legendary Gem City — a place where each child finds a magical gem that grants them an extraordinary power. Together they forge a bond stronger than any crystal to face their first great threat.
Darkness returns in the form of the fearsome Ender Dragon and an immortal villain who turns out to be their own cruel neighbor. When their powers are stripped away, the children discover their parents are legendary superheroes — and that family is the greatest magic of all.
A forgotten map leads the siblings and the lightning-wielding Celeste back to the Ancient Gem City, where they uncover the Heritage — a sacred realm granting immortality. Now eternal guardians, they face a dynasty of thunder-animals, a moon-born robot, and an ancient venomous cobra.
A borderless Yin-Yang portal tears open in the Heritage, unleashing the obsidian warlord Pyroblack and the storm demoness Darkstorm — rightful heirs of a stolen empire. With Gronk fallen and their gems drained, the 17 protectors must survive long enough for a Godly Ray to reforge them into cosmic legends.
