I probably watched all of about two or three episodes in total of this French-Japanese animation as a child but thanks to the beautiful animation, stunning visuals and the beyond epic theme song it has stayed permanently embedded in my psyche ever since.
Now as I have the chance to watch every episode from the beginning, there are two things that stand out to me; (1) I was shocked to learn that it originally aired in it's entirety before I was even born and (2) I am only about eight episodes in and already I can see why this resonated so deeply with many eighties kids, like myself; not only is the animation beautiful, but the story, which centres around Spanish exploration of the Americas in the 16th century, is very mature and the characters incredibly engaging and complex for a children's show.
While the adult characters are driven by very 'adult' motivations of seeking fortune and notoriety in finding 'The Mysterious Cities of Gold', the children are driven by much 'purer' motivations; Esteban, a young Spanish boy who lived his whole life believing he was an orphan learns from a man named Mendosa that he is a 'Child of the Sun' and that he was rescued at sea by Mendosa himself and his real father may still be alive, somewhere in The New World, close to where he was rescued.
Zia, a young Incan girl, who was taken from her family and captured against her will by Spanish explorers, wants to reunite with her people but is conflicted because in doing so she will lead her captors straight to them.
And lastly, Tao, who joins the story a little later, is the last remaining member of a technologically advanced race who believes he will discover the secrets of his people in the Mysterious Cities of Gold.
If I had to nitpick anything, it would be that while Esteban, Zia and Tao are all implied to be around the same age, in the English dub, Esteban sounds notably younger than Zia and Tao, who both sound like the preteens they're supposed to be. Esteban sounds like he's about eight years old. But that's a really tiny nitpick.
I wish I could could say it's my age making me say 'they don't make them like this anymore', but they really don't.
