Since Eruption Day, the climate of the world has been altered significantly. Not only have weather patterns been affected, the average world temperature has dropped and the ice has more claimed large tracts of land for itself. The world as we know it has been plunged into a sort of premature ice-age, with the temperatures not as cold as the last ice age and less ice covering up land in the north.
