This is just a concept I've had lying around. Tell me what you think:
The world has fallen. Not into darkness, but into Twilight: Where the Sun cannot reach and Night refuses to venture. The world seems to be dying, say most experts as the seas begin to shrink and deserts begin to grow. Humans and Anthros are alone in this dark world, with the humans outnumbering the Anthros and often discriminating them. Time is running out and people must decide what to do: Do they try to endure it and remain simple civilians? Do they take advantage of the situation and embrace the Twilight? Or are they one of the brave few who shall risk their very souls to bring light (or complete darkness) to the world?
It'll probably be rather open, although it should remain as serious as possible. Depression, death, suffering and traumatic histories are all welcomed with
wide arms.
(Edit: If I don't get any replies soon I'll set it up and see how it goes from there.)
