Set is portrayed as the usurper that killed and mutilated his own brother Osiris. He is one of the Egyptian Nine Ennead. A god of the desert, storms, disorder, violence and foreigners in ancient Egyptian religion. Set has a positive role where he is employed by Ra on his solar boat to repel the serpent of Chaos Apep. Set had a vital role as a reconciled combatant. He was lord of the red (desert) land where he was the balance to Horus' role as lord of the black (soil) land. Set's siblings are Osiris, Isis, and Nephthys. He married Nephthys and fathered Anubis; and in some accounts he had relationships with other goddesses. 
Thuban's Role in Hijack of Set
Orion Group linked Thuban controlled AI architecture into the planetary mind and the stargate systems, and this infiltration began the hijack of organic stargates. This was achieved through the building out of alien machinery designed for anti-life inversions that promoted satanic blood ritual and AI run Black Magic sorcery throughout the Planetary Grid Network.
Thus, humanity through the Egyptian world culture at the time of invasion were taught to worship Thuban as sacred to Set or Typhon, which is synonymous with the use of fire as an aggressive force of weaponry to represent those whom are Opposers of God. This Egypt timeline is worshipped by the controlling power elites, as they believe this is when their Gods were on the planet and put them in charge, to rule Earth for their personal pleasure and on behalf of their Alien God Masters. As the global human culture was systematically invaded, every wisdom teaching was stolen and hijacked, every natural spiritual ritual was infected with Blood Sacrifice, Black Magic or blood cult worship. Through this systematic process those who participated in blood rituals would emerge to be the preferred bloodlines and were rewarded with immense power, wealth and protection from their enemies. Then came the conditioning of Sexual Misery programs in which sexual perversions and gender reversals would be practiced in the context of sexual blood magick to please these Alien Gods, while its inherent design was loosh harvesting and to invert and destroy the male and female balance in the world.
Sodomy and anything connected to the rectum or feces is sacred to Set or Typhon. Thus, sodomy was introduced in blood rituals in order to generate Typhon Tunnels, this is used to reverse life force from its natural direction and channel powerful demons aka Alpha Draconis Black Sun entities into the material plane. The Typhonian tradition is sometimes defined as a current that flows through the cosmology of the Order Templi Orientis (O.T.O.), established and made famous in current times by Aleister Crowley. The OTO rebranded Typhon as the feminine aspect of Set, in which this aspect of Alien Dark Mother became of supreme importance in the formula of sexual blood magick, designed to hijack the Founder’s Christos-Sophia Rose lineages and to produce demonically enhanced moon children rituals in its place.
