But the angels were envious. Descending to earth, they sowed hatred and discord among the previously peaceful tribes of Nевендаар. Malice and greed gripped the hearts of the sons of Betrezen, and the Humans waged war against their brethren, sweeping away everything in their path. And the beauty of Nевендаар faded before the horror of the war unleashed by Man…as you can see, the angels did not curse anyone, but simply sowed Chaos and Heresy in the hearts of the inexperienced.
The Almighty looked upon the lands of Nевендаар and was filled with sacred horror. Where was the harmony that Betrezen had spoken of? Where were the endless green pastures? The Almighty saw only discord and suffering, only the land scorched by merciless wars.
And divine wrath shook the heavens. For Nевендаар was not destined to become the pride and joy of the Almighty: Betrezen had betrayed his Father. And the rebellious angel was punished and banished to the Chaos forever. And then, filled with great wrath, the fallen Angel created a merciless horde of demons. So that, if not himself, then his earthly servants would take revenge on the ungrateful human race…
Betrezen's hatred further fueled the bloodthirsty demons: they were only waiting for the moment when war would completely exhaust the human race. While awaiting the appointed hour, the demons turned their predatory gazes towards the elven forests...
The people of Betrezen followed him and were cursed by High Fazer. Consequently, it is impossible to enter Hell and remain uncursed.
and in the "Chaos," where Betrezen went, there were already demons. It is Chaos, after all. There are always demons there, aren't there?
so some of them - imps, gargoyles, for example - are demons "by nature."
and others, such as Modeus or a succubus, are precisely "cursed" people who ended up in Hell after him, and therefore, thanks to High Fazer.
I read this somewhere before;)
