Eldorado Muisca, Origin of the Legend and Fall of the Chibcha Nation.

The Muisca nation gave birth to the legend of ElDorado. The legend spread due to the ritual done to crown a new king, a zipa. This ceremony was celebrated at Guatavita`s lagoon. The upcoming zipa was completely covered with gold powder until he became the personification of El Dorado, a golden man. Afterward, he dived into the lagoon, copulating symbolically with it, and become the undoubtful zipa.
The news of this ritual walked the paths as far as Quito, where Sebastián de Belalcázar heard about it. But this is not a novel of some primitive and noble savage, that romantic idea that has over three centuries. Not the superficial idea of Muiscas their descendants, (half-blood too) have. No, instead, the real History of a developed nation with politics, economy, hierarchies, riches, lords, palaces, goldwork, and a powerful and stable kingdom.
This novel asks for the right place in History for this culture. In a rich evergreen land sparkled with lagoons, surrounded by páramos that give birth to crystalline rivers, with a favorable climate, the History development is surely different than that of a culture in the middle of a desert. The reader has the opportunity to live in Bacatá, as a Muisca, and watch six decades of their affairs. Then, strange news arrives, unknown and weird people are coming, they bring horses, steel armors and swords, and gunpowder.
The Muisca nation is confused, not sure if this strange men are gods or enemies. Conquerors come for ElDorado, they want the gold, and even though Nature has not placed gold in this geography, Muiscas have been rich and accumulated tons of it. Each cacique has its treasure, and each Ubsaque has its own, but they will bury it before giving it to the Spaniards. It seems the final day has come for Muiscas.
How can they defend their nation?
