As it turns out, they were all wrong, and the world will end in butterflies.

It was almost calming, something like a lullaby, every colour a death, every wing a soul.

It had gone so well, for so long. Magic and technology fused in incredible ways, advancing the world beyond all recognition.

War was a thing of the past, horror stories told to children who would never experience want, hunger or pain.
And yet, those who had lived through that final, terrible conflict bore their scars, driven beyond all reason. Driven by loss, grief and anguish, there were those who did not rest, could not rest, until they achieved all they could achieve.

They had changed the world, driven Darkness out by shining a light so bright it blinded those around.

And in that second was a kaleidoscope, new light erupting onto their faces, and they knew all the colours.
