What happened in the 'Spell'

It was Political and Religious Persecution. A Political and Religious Takeover, Movement (and 'Push').  

Also: Persecution of 'Deux', the 'Unpenitent', Holy men, believers in Christ (and therefore) who are faithful/obedient, the 'Opposite' as they used to call them...*

*[See also: "When everyone is corrupted...then what happens? The Earth's Energy Signature is the reversed. And why would that be desirable? For Holy energy**, to Make Clean what is Unclean. -To be Clothed, rather than Naked, but not with Christ's Righteousness].  

**Holy (energy) they call: Counterfeit, Deux, False Light, False Fire, a Base Layer, Inferior Energy 

It was also a 'takeover' involving different Species. Such as: Abbas, Female Angels, gods...
