What is archfeyy??

Hello since i am kind of new to dnd and had the courage to create a homebrew world (not a good idea) i have quastions.

I created this Universe; OTHIMAS. gods and the universe and the planets are already planned.

Now my gods are all good alignment (some neutral, some chaotic some lawful). Cause i didn't want some of the character or npc says "I believe this god and this god order me to hurt you". Its not for me and you dont need to give gods evil alignment, if someone want to be evil or do evil things they will find a way.

Whatsoever i want some of the creations of them to turn evil. Cause of jealousy, hunger for power, want to live forever etc. And them to crate evil alignment things like monsters, demons, beasts etc.

So i need some beings like archfey ,archmage and entities but i really dont know what are these. Or what are the close beings to them. What kind of races or beings i can use ?

The gods creates them and the others. But they are the ones who is older beings and has more power or influence over world then normal human beings.

And their influence will overlap with the gods and makes the world in a chaotic and corrupted place. (But some of them will blame the god [God of Death -SONA] and this evil will be attributed to the God. People and worshipers will think that he commanded and created evil. And this will disrupt the order and balance of the planet creating a barrier between the gods influence and the planet Lios. And making some riots and monsters to appear.) But not ALL of them are evil. Some of them will be good or neutral.

Soo please help me🫠
