I'm generally not a fan of the D&D esque alignment charts. It's too simple and narrow focused. It assumes a general sense of morality, that we are all broadly one thing or another, when morality wise we're not all black and white, nor even shades of grey, but a vibrant kaleidoscope of colours.
On the loosest level this seems about right. Though "dark" and "light" as moral concepts is a tad confusing. Dark and Light are both elements that are part of the world of RuneScape and are as vital as one another for a balanced world.
But our gods are a bit more nuanced than this chart suggests and will deviate from their "alignment" in the right circumstances.
Also where's Brassica Prime? Bestest god.
