Shadows of Evil
We have all played the games where the heroes come together and defeat a greater evil, but what would the world look like if a group of evil heroes came together and defeated a greater good? In time the world would settle down, though without the underlying essence of good in people. This is the age of guilds and organizations, and less the age of clerics and churches.
This campaign is set after the world was shaken up by such a campaign of dark heroes. So what will happen in this world? Will the darkness grow? or will new heroes emerge to bring light and hope back to those who have never known it.
