Can mortals have Discord?

No. It is a purely celestial problem. Mortals can certainly suffer some of the ills which, in a celestial, are outward symptoms of Discord, and the character point effect is the same (see the Corporeal Player's Guide) for these disadvantages.

But it is not really Discord. For instance: in a celestial, being Crippled is a sign of a stained soul, but in a mortal, it is a sign of an amputated. Likewise, a human who has a mental problem is not touched by the Pit.

(In Nomine, p. 63, states that Ethereal Discord can be gained in ethereal combat. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
