I haven't watched the video yet, I will soon. But, I'm familiar with the archons, because I have read most the manuscripts found at Nag Hammadi. All civilizations have been talking about demons, archons, jinns, morgellons or whatever other names they use. In Gnosticism, archons (Greek for "rulers") are malevolent, semi-hostile beings that govern the material universe and act as jailers to trap human souls within the physical realm.

They are led by the demiurge, a flawed creator god who fashioned the material world as a prison. Seems familiar? archons are nothing but entities the demiurge created to assist him in enforcing ignorance and separation from the divine Pleroma. The best description of the demiurge I found is in the Apocryphon of John. "Now the archon who is weak has three names. The first name is Yaldabaoth, the second is Saklas, and the third is Samael. And he is impious in his arrogance which is in him. For he said, 'I am God and there is no other God beside me,' for he is ignorant of his strength, the place from which he had come." - Apocryphon of John

The last part of the quote is found in the OT, and if you pay attention it's all beginning to make sense. Both John and Isaiah are talking about the same entity, the same jealous god, or the leader of the archons. "I am the LORD, and there is no other; there is no God but Me." - Isaiah 45:5
