The ocean wars saw small fish cowering in any shelter they could find while the leviathans of the deep cruised in search of things to kill.
What they found was each other.
The waves bloomed red and the sea foam blew pinkly in the breeze.
For a while, the kings and queens of the deep ignored the carnage.
But even they had to awaken to the disaster that stalked above their heads and broke the silence of millennia to agree this must stop before the great predators made themselves extinct.
The killing stopped, but not before whole families died, unmourned.
