Our beautiful world was torn in half.
Once, the world was calm, peaceful, fully known. We had no questions about the world we lived in--certainly, philosophers waxed eloquent about the possibilities of afterlife, the old superstitious concepts of an Outworld, full of daemons, but it was more an academic exercise. In the last two years, though, we have realised how wrong we were to ignore those wise ones.
Strange things happen daily. People disappear, bodies are found sacrificed on strange altars, animals scatter when nothing is present, birds take flight in strange new patterns, and some even claim they see blood in the sky. These are read as omens by most people; they consider them signs of pending doom from Outworld. Meanwhile, others claim that the sundering of the world is a time of excitement, of opportunity for exploration, redemption, salvation.
