From the Ghost Land in the north to the Silverpine Forest in the south, almost half of the Eastern Continent had been completely covered by the Undead Catastrophe's plague power. This plague was not merely a virus that could turn living beings into undead creatures; it was also a form of magic imbued with curse power. Under its influence, the land that had just begun to recover from the corrosion of the Undead Catastrophe was once again turned into a wasteland reeking with lethal poison mists and blackened with decay. The heavy clouds polluted the already gloomy sky and refused to dissipate, filled with a modified version of the plague virus. Even birds that happened to fly by knew to detour far away from this millions of kilometers of thick poison clouds. Beneath this contaminated sky, it was difficult to find a single ray of pure sunlight on the whole of the corrupted land.
