When Gods Cry; Pain is Our Prayer.
Burning of City Piu
Not much is known about what actually happened to cause the great explosion of arcane power. Some think it may have been Shadrab’s plan-B to send the remaining Old Gods away from the material plane. Whatever the cause, 45% of the world’s population was instantly destroyed, vaporized by the explosion, and those who survived the disaster found a large glowing ball in the center of the city. What little research was allowed before the Three Kingdoms arose and took control showed that the energy ball was some kind of second impact that failed to detonate.
