Whalefall

The singing stops as abruptly as it began. The dark cave water is riven with luminescence that brights it in quicksilver. The leviathan expels gant from its spout which begins to devour the bright, blotting it out until your craft bobs in complete darkness.

A final note emerges from the nothing. I have lived long enough. Then there is scent of rot as something vast passes by, rocking the boat to and fro. The midnight whale moves.
