They'd heard it many times through the ages, Luna's Song. She sang while a mere crescent, her silvery light repairing souls, their inner selves.

But through later centuries, she struggled for her voice to be heard as apathy towards the old ways grew and her song weakened and her people, in turn, became deaf to her melodies.

Great Goddess All, impatient at their folly and hurt by her sister's plight, withdrew her protection that reflected dangerous rays from the sun. The sun turned bronze in an opaque sky and as it grew in size, so intense was the heat that the planet began to crumble into dry dust.

Within caverns set deep inside coastal cliffs and high mountains, a few hardy people remained living off cockroaches, bats and rats and, in their hunger, thirst and despair, remembered too late Luna and her song.

And as the last survivors prayed, promising Luna that once again, they'd heed her song, a silver lining, filled with dark, grey cloud, covered entrances to those caverns sealing inside every man, woman and child for ever.
