I don’t know if this’ll do anything for you, but I don’t think you need to explicitly avoid making the light dragons “monster-like”. Even if they do mirror the Kuros, there’s a lot of room for moral grayness, and the opposite of something “bad” isn’t necessarily something good. Personally I find it interesting when people buck the light = good / dark = bad trope, but maybe that’s just me ¯_(ツ)_/¯

OOC : I get what ya mean, and I think that’s what I’m going to try my best to go for. I just noticed that that is a trend in a lot of my stories and has been ever since I started giving my characters stories, as I grew up in a rather broken and somewhat dysfunctional family. The people I was suppost to trust and love turned against me when it benefited them, and while most of my family does love and accept me for who I am, it’s left me with some mental scars I still struggle to fight against. 

That really shows in how I write my characters and stories, like I feel a personal distrust of things that are meant to be the good guys, but really they’re far more corrupt than those that openly admit it. I don’t want to do that to the Light Dragons, I want them to be the true good guys, and I agree with the moral grayness. Whats good to some may seem monstrous to others, I really would like to write the Light Dragons with very similar morals to the Kuros when it comes to keeping the balance of a chaotic universe. I’d rather them NOT end up like Warfang x,D
