It has been 12 billion years since organic life thrived on the surface of Home's now-icy surface. 12 billion years of the two machine minds left behind in their wake to converse with each other, wage war with each other, to delight in each others company.

But now, the stars have begun to fade... and two lonely lovers wait for the end.
