It is generally stated that the Middle-Ages were "times of darkness and misty terror." Miguel A. Fernandez in "The Eclipse" contradicts this statement and describes how after the suppression of the Knights Templar Order during the 14th century, all heroic ideals that ambitioned to provide men with sovereignty and freedom became progressively cursed, defamed and eclipsed. In this second book of "The Solar Warrior" trilogy is exposed how conformism, convenience, self-interest and the fragmentation of all things deeply invaded the spirit of the men of the West since the 14th century, causing mankind to lose precious knowledge of the cosmos, which became subversive, and ultimately constituted a complex of powers already defined in the previous book of the trilogy "Origins, Rise and Decline" as the SuperDragon. This eclipse of the incarnation in men of the primordial warrior light took place in parallel to the counterattack of a new power-structure that deeply mutated the terrestrial biosphere in a matter of few centuries: the Techno-System, a completely new environment, visible and invisible, which provides comfort, power, energy and material resources to humanity, yet at the expense of rigidly chaining its freedom and its actions to the world. In the first part of "The Eclipse" is described the progressive advance and proliferation of such Titanic megastructure, fuelled with the smelly fire coming from the hellish terrestrial subsoil where the SuperDragon roars. The organizations and ideologies that became decisive accomplices of this development at a planetary level are also pointed out. In the second part of "The Eclipse" are described the essential characteristics of the Techno-System by means of an adequate and rigorous approach to systems physics, thus providing an operative and technical knowledge that all Solar Warriors must deeply come to terms with in order to apply within the conditions of existence of the 21st century those heroic and Solar principles that have early been discarded and cursed by the champions of official History in the mists of time. Miguel A. Fernandez draws in this book upon the cultural heritage of the West as upon the work of "cultural heavyweights," such as Theodore Roszak, Joseph Needham, Lewis Mumford, Friedrich Nietzsche, Jacques Ellul, Max Weber, Julius Evola, and hundreds of other referenced authors. "The Solar Warrior" trilogy is composed of two other books: "Origins, Rise and Decline," and "A New Hope." In addition to this book trilogy, Miguel A. Fernandez is also the author of the free novel: "The Solar Doctrine."
