As disciplined as humanity is, people fear a lot of things. Fear is something you simply can't get rid of, it's ingrained in your instincts. There will still be monsters of many kinds. People might be able to fight and not be frozen by fear, but lots and lots will die. As of now, Humanity's only a few thousand in numbers. With this, their numbers will go down to mere hundreds, and that's not enough for a viable population, they'll die out.

So, I petition someone to end the Eternal Darkness. The God who does it will earn point of awesomeness with Astarte. Reason she won't do it? It's entertaining to see what it is mortals fear and what they feel when hope is gone.
