The whole premise of travelling through time and space seems really cool from the very beginning... If you don't think too hard on it. Due to messing with eldritch technologies, Juan Salvo becomes the Eternaut, the "Traveller of Eternity", travelling through time and space over and over. This means that he was able to escape the likely complete extinction/enslavement of the human race, but he can't control this power. On the other hand, the same thing happened to Elena and Martita, his beloved wife and daughter, both also drifting through the many continuums of spacetime together... hopefully. So Salvo faces the tragic condition of being Last of His Kind, knowing positively that his family is somewhere out there, jumping through time and space, facing the endless dangers and horrors of the universe on their own, with an infinitesimal chance of ever finding them. Needless to say, he holds onto the hope that he will find both, asking about them to every single creature he meets. And he finally does... In a way... or does he?Who knows.
