A land or world where the sun is harsh and brutal, and the night is the time when people can actually safely come out and do stuff, and a people who regard the night as a time of creativity and magic and mystery (after all, anything could be out there, beyond the range of the torchlight), and the sun/day as a brutal oppressor out to burn and blind them (and the darkness as a protector, sheltering them from the merciless sun deity), could be a fun twist on things.
'Cause yeah, it's always light good, dark bad. Nyx, bad evil goddess from before time. The darkforce dimension, not terribly fun place (Dagger, for instance, has no cruel hungers stemming from a 'lightforce dimension' and her powers aren't quite so traumatic or terrifying even to people she's trying to help!). Etc.
And that's pretty tired, even when it's not twisted up with racial bias and colorism.
I remember when the 'Earth Force' came about, there was Wind Warrior, who seemed based loosely on the powers of the rain goddess Tefnut, Skylord, based on the skygod Shu,
and uh, the big guy, based on the earth-god Geb. And yet Geb's wife, the goddess of night, was mysteriously absent. Making them a quartet, reflecting those four gods, would have made more sense, but it seems a heroic character based off a night-goddess was a step too far. (Or maybe it was her name, which begs for mockery. Nut.)
