Realms are stored in gems. Like voodoo dolls, when the gem is harmed, the realm is harmed, and the story it contains cracks, causing a conflict. Therefore, to protect the beings inside a gem, they must be guarded by gods. These gods not only create the gems, and protect them from all evil harm and help each being inside to find a happy ending, but they also set the laws of the world. Most of the time these laws are delicately placed to avoid harm, and to keep everyone happy. They're flawless, and admirable, and that is why the beings look to the protectors as gods. However despite the perfect appearance, nothing is perfect. A single flaw can slip through, ruining the lives of thousands and setting off a snowball effect. This is that snowball effect in action.
