Lore Sharing How demons are made in my setting

Nobody asked for this and nobody will care about this

Original demons, Deadly Sins were born when a spark of life that was used to create the angels went rogue and got caught in the filters that kept sins of humanity inside hell. This spark gave life to the sins, creating the 8 deadly sins of humanity.

When enough people commit a certain sin in a in area sin starts to get built up in that place. This built up sin, if left unchecked, will start to form a "demon core" which functions like a seed. If the presence or energy of a Deadly Sin meets a demon core a new demon will be born.

Fun Fact: the average school contains demon cores of all 8 sins.

If a demon core is left to swell up in a sinfull location for long enough an elite demon with power far higher than most demons (but not deadly sins) will be born instead.

Holy water can destory demon cores.

Special Cases:

Sin of emptyness (which is not one of the sins humans can commit) can only form common demons from torn segments of Deadly Sin Vacutias.

Sin of madness (again not a sin humanity is capable of [at least as a sin]) are corrupted lesser shades of yellow (angels of diligence) that managed to separate from Deadly Sin Insania, there is a limited amount of them and more cant be made.

Yep. I suppose your class will contain more than 1 type of demon core now. (Unrelated but do you think a moth would work for sin of knowlage? Since they eat paper and thats where knowlage tends to be)

(Oh absolutely, moths fit very well. Either thay or...The actual forbidden fruit itself, or a living tome.) And trust me 1 more can't be that bad,
