Fear not. Countermeasures have been deployed.
And perhaps these meddling mammals should pay attention to the prophecy of Ragnarok:
Prose Edda wrote:
"Then will occur what will seem a great piece of news, the wolf will wallow the sun and that will seem a great disaster to men. Then another wolf will seize the moon and that one too will do great harm. The stars will disappear from heaven. Then this will come to pass, the whole surface of the earth and the mountains will tremble so (violently) that trees will be uprooted from the ground, mountains will crash down, and all fetters and bonds will be snapped and severed. The wolf Fenrir will get loose then. The sea will lash against the land because the Miðgarð Serpent is writhing in giant fury trying to come ashore. At that time, too, the ship known as Naglfar will become free. It is made of dead men's nails, so it is worth warning you that, if anyone dies with his nails uncut, he will greatly increase the material for that ship which oth gods and men devoutly hope will take a long time building. In this tidal wave, however, Naglfar will be launched. The name of the giant steering Naglfar is Hrym. The wolf Fenrir will advance with wide open mouth, his upper jaw against the sky, his lower on the earth (he would gape more widely still if there were room) and his eyes and nostrils will blaze with fire. The Miðgarð Serpent will blow so much poison that the whole sky and sea will be spattered with it; he is most terrible and will be on the other side of the wolf."
They want chemical warfare? Well, they asked for it...
I love the Eddas. Brings back memories of my father reading them to me before bed.
