The first complex story arc: The King of the Orcs

Currently I am implementing the first complex story arc for JADE to show off what I am considering to be one of the hallmarks of future versions: complex, long-running stories that can influence your game in various ways depending on how you interact with them. Despite being spoilerish in many ways I would like to explain the basic setup based on the "King of the Orcs" story arc that will be introduced in JADE 0.2.3 and serve as an example for many more story arc types to come.
