Yes, I have fallen. I fell to the sunless and cinder-choked land below and was stripped of my boons of agriculture, but I gained more in exchange. I could, say, teach you an alternative to a thermonuclear weapon that doesn't bathe the blast site with radiation or teach you the true solution to reversing the warming of the air of the mortal world. But I require a gift in return. Choose what you desire wisely, mortal.
