If Aeneas escaped from destroyed Troy to cross a sea unknown and found a distant colony which would be the birthplace of an empire, Rome and the first Aznar lead the survivors of the invasion of Earth by an alien species to a distant star to rebuild the lost homeland, Inci thereby in the collective ownership of the people valerano (Valera, an original 'autoplaneta') were heirs of mankind.
In Saga, futuristic technology meets a very specific logic and originality: 'metal hyperdensity that repels the gravity low electric induction', ships that simulate cetacean space forms, the sidereal armed with millions of ships in battle over the fate of mankind, Z-rays, "sunlight" as a lethal weapon or as interstellar propellant, and the fabulous machines Karendon (inclusive of the field as the famous Star Trek transporters but brought here to their logical conclusion).
A future society where the players have all the elements that characterize it as utopian, where money has been eliminated and automation has freed the human race from work.
The novels allow the reader to accompany the vicissitudes of mankind through family members of the first protagonist (the aviator Miguel Angel Aznar de Soto), who is thrown from the contemporary period, after an adventure in search of 'flying saucers' in the Himalayas, to an unlikely but highly suggestive Venus' Jurassic, and finally to five centuries in the future with the Earth on the brink of a dreadful World War and the shadow of an even more horrific alien invasion looming.
Pascual Enguídanos not only achieved a long series of novels, but managed to keep a cycle of tension and growing interest, by constantly evolving the plot and characters.
