The Sorceress sends He-Man to Etheria, telling him that She-Ra needs him urgently. On Etheria, He-Man finds himself surrounded by intense war and chaos, as the Horde bomb a small city. The villagers escape to the mines while She-Ra and He-Man fight the Troopers, then they explain to the heroes that the Horde attacked their city after they ran out of Etherium, a substance they were mining for the Horde. The Horde are planning to burn the city, but the villagers tell She-Ra and He-Man that they no longer care about saving their homes- all they want is freedom. As She-Ra heads off to get some backup rebels, He-Man does his best to help the villagers survive in the mine. Amidst all this war and suffering, the villagers realise that they must join the rebellion and fight for their freedom.
