Compliments of Anabstercorian, the people of the northern Flanaess are experiencing something new and awful.
Radiation sickness.
The 150 hits in the Godspires released a great cloud of it, and it is late autumn, so the prevailing winds are west-northwesterly, especially in the upper atmosphere.
The radiation blows southeastward over all of Blackmoor, then all of the Empire of Iuz except the far south.
Then, in spreads over all of the League of Warlords (whose entire population just mysteriously disappeared, which is becoming like a broken record, I know ...), then over all of the Alliance of Delrune.
The cloud spreads over the northern half of the Union of Oerth and all of the Thillronian Peninsula.
The people in the northern Empire of Iuz and in Delrune are the most affected, and there is widespread radiation sickness.
Magical healing has no effect on this illness.
A Heal spell, or Regeneration, or Restoration, is needed to halt the onslaught of this strange illness (that is not an illness, but a breakdown of the body.)
Many, many people die across the northlands, and there is widespread panic.
Nobody is familiar with the term radiation.
For these people, it is a strange illness from the blue, which is impervious to all normal efforts to stop it, all herbs, and even most magical spells.
Tokiwong and Creamsteak are soon up to their ears in troubles, as thousands, then tens of thousands, of people fall ill.
