Evil Light

The Light seems like a good, kindly thing, especially compared with that bad old Darkness. Whereas Darkness is usually concerned with kicking puppies, eating children, and laughing its head off, the forces of Light generally worry about nicer things, like singing with the birds, helping little old ladies cross the street, and... well, you know, being a Hero.

However, the Light isn't always what it appears to be. Sometimes, a battle with an obviously Light-wielding character will not result in Defeat Meaning Friendship or an Epiphany Therapy, but will just end with a laser-scorched corpse and the shiny happy killer skipping off to continue using their sunshine-fueled powers to wreak decidedly unholy havoc. There is a reason why the word "Light Bringer," in Latin, literally means Lucifer.

It turns out that, just like how sometimes Dark Is Not Evil, sometimes Light Is Not Good. Some will view the Light itself as natural, and darkness as nothing more than an absence of it. Others will see Light as a destructive force, a perversion of the infinite all-encompassing Darkness.
