Allow me to give you all a terrifying scenario on this lovely Halloween night! I am thinking of depicting a semi-apocalyptic event happen in my fantasy series. This age of darkness will be caused due to a massive imbalance in the natural order. This imbalance will be caused by the excessive usage of dark magic and necromancy so that an overly ambitious few can be immortal. As this imbalance increases in intensity, the nights will be longer and darker, the screams of the damned will be heard for miles, and unholy creatures will lurk in every shadow. As necromancy is tinkered with to higher levels, worse undead abominations than zombies will appear in the darkness. One of the major obstacles the heroes will have to overcome is destroy the source of the imbalance and bring light and life back into the world.
