I Don't Understand the Light Theme

[ApolloGenX]

So youre confused about light producing angelic seeming monsters but not confused about Darkness producing demon seeming monsters like Diabolos?

I don't consider primals.... they can look like anything.... but yes- given the explanation, I don't know why dark would produce demonic style creatures, either. In fact, if they are not elements, and more of a polarity... maybe they would even look the same, but have different color themes...if astral and umbral are surrogates but not equivalents for good and evil....good and evil creatures might look the same...possibly color difference for stylistic flair, but you can't tell just by looking what something is...
