Archons are a species of inorganic beings that emerged in the solar system prior to the formation of the Earth. Not only that but they are also revealed to be the servants of the Demiurge whom appear as an alien force that intrudes subliminally upon the human mind and deviates our intelligence away from its proper and sane applications.
The Archons are a genuine species with their own proper habitat, and may even be considered to be god-like, but they lack intentionality (ennoia: self-directive capacity), and they have a nasty tendency to stray from their boundaries and intrude on the human realm. Archons are said to feel intense envy toward humanity because they possess the intentionality they lack.
They are not what makes humans act inhumanely, for humans all have the potential to go against their innate humanity, violating the truth in their hearts, but they make them play out inhumane behavior to weird and violent extremes. The Archons are forces that act through authoritarian systems, mainly through the request of the Demiurge, including belief-systems, in ways that cause human beings to turn against their innate potential and violate the symbiosis of nature.
Despite their seemingly malevolent nature, the Archons are not evil in the sense that they possess autonomous powers of destruction, able to be applied directly upon humanity. Instead they are agents of error rather than evil, but human error, when it goes uncorrected and runs beyond the scale of correction, turns into evil and works against the universal plan of life. Gnostics taught that the Archons exploit our tendency to let our mistakes go uncorrected.
