The vault is shut.
The lights in the sky flicker out, not directly seeable above the layer of clouds now covering the entire planet, but wizards and other spellcasters know. They cheer, and go to cry the good news to others.
Not nearly all clerics, but a few clerics here and there, of eighth or ninth circle, receive faint touches of reassurance from their exhausted gods. They cheer, and go to cry the good news to others.
High on mountains, here and there, above even the clouds of war, metallic and chromatic dragons watch the sky's lights fade, and raise their heads and bellow victory for Good and Evil.
It's still raining, of course, clouds don't just vanish when the gods stop stirring them. But now the rains will grow lesser rather than more, and soon in many places they will be gone.
Merry Christmas.
