The Mysterious Cities of Gold - S3E16 - The Black Suns

I get that they have pseudoscience behind them, but it feels more like D&D and therefore more fantasy since wizards could have orbs circulating them for weapons at least for 4th edition

Esteban crashes into the village and they set off trying to get the sword out of the wing. Meanwhile Kokapetla arrives with the message from Anatos that confirms that the maharaja is drugged by some American herb extract that takes away someones willpower. Zia then begins concocting an antidote from the village healers supplies. At dawn Esteban gets the sword out with the elephants help and as Zia arrives they fly off.

In the meantime Mendoza and the others are taking the underground tunnel to arrive at the factory. They just missed Tao getting the final plan of Ambrosius laid before him after Ambrosius discovered that Tao visited Anatos. Ambrosius plan to create the weapons of the Mu empire and use them to conquer the world since the current rulers are not worthy since they aren't geniuses like Ambrosius or Tao, that Ambrosius sees as his heir. Tao is locked up in his cell after been shown the power of the Black Suns, orbs of oricalcium that is used with the telekinesis crown and able to fire beams of some kind, burning up coal at least. Mendoza and his gang knocks out the guards and as Esteban and Zia distract the guards at the fort, they free Tao and heads for Anatos cell. They are intercepted by Laguerra who have been looking for a rematch with Mendoza and after Mendoza hands Tao a purse the duel is on. Zia drops off Esteban that goes straight for the maharaja to cure him with an antidote dart so that they can get the palace guards on their side. But Ambrosius had anticipated this and awaited in the throne room with the crown and Black Suns ready to kill Esteban.

The documentary was about elephants and motorised rikshaws as modes of transportation, both ancient and modern.
