I have admittedly never played any of the games affiliated with Dark Souls, so while that is not my intent, it might be a good place for one to imagine as reference. I do know it is a very grim world, and pretty steeped in its mythos. Short of that, [@HopelesRomantis], I believe your idea is much in line with the concept I intend to go with; "optimists and improbable heroes against a far superior threat".
