She cradled the faun's head. She listened to its soft breath, listened to its complaint, listened its petition. But what could she do?

At night under the moon she called her sisters, who had all once been close, close enough to be one, but now far and spread. They came if they could, sent emissaries if they could not. They talked until the edge of the sun, bloated and red, crawled up past the horizon. And a course of action was decided upon. War.
Nature unbounded is a fierce thing, given time. But even faster, the edges of grasses became razor sharp, cutting through rubber and stone, metal twisted under the weight of unrestrained flora. Vines pushed through the remains of what was vast concrete deserts, flowers sprouted all over the detritus of humanity, using the reflected sun of a thousand glass windows for strength.
Humanity fought back of course, with cruel weapons and ingenious tactics. But ultimately, nature won. Nature always wins. You can't fight the interminable drip of water, it wears down even the strongest stone, washes away every trace. Wood and leaf and flower and thorn, these were the tools that all of nature used to reclaim space for itself.
