The greatest threat to humanity is mankind itself. No matter how hard you try there will be people who don’t do anything at all to save their own kind. There's only one thing you have that will bring the light to all. Hope. Hope will not only save the people around you, but it will bring light to the ones you least expect. Throughout your journey you will see people crumble. Hope can’t save everyone. Hope will only give you the light you need to push forward through the darkness. Some will get lost forever in eternal darkness and some will walk to the light. Your efforts for saving mankind will come at cost but you'll make it to the end, as long as disaster doesn't burn out your light. Only you have the power to have your light guide you home
