Hypercalcemia

All lies dead. The planet's core grew cold a billion years ago. The sun is distant, a dot in the sky whose light is but a pale reflection on the icy moon. No plants remain to groom the surface nor tend the layers of the sky. Nuclear winds bleach the bare bones of mortal civilization and Earth is just a lifeless wasteland howling through the void. But death is just a substitute for life. And life always finds a way.
