Ethroa is an android built to counter the reign of Nimhoa. Both androids were generated in the same furnace at the edge of the galaxy, but Ethroa has limited energy. Once the interplanetary threat is eliminated, it will have to shut down forever. The concept of intelligent androids is a recurring element after the 2000s that I will carry with me for another decade, the emblem of a conjunction between the post-human and the artificial machine.
