Dungeon Mastery: The Big Bad...

The direct cause of much of the world's ills, the Big Bad exerts a force across the story arc during which there will be numerous confrontations, their presence driving the plot. In the end they are too powerful.
The Big bad works through minions through the story arc, and employs Dragon level protection. They function at the Mythos level, rather than the story level and can be considered non-threats simply because they are functioning well beyond the level of the PCs.
