Silver Devastation

The Silver Devastation is an area of space in the Isop Galaxy where two galaxies collided some hundred billion years ago. This vast sector of space contained nothing but dead Stars and dark matter. From a great distance it looks like a huge silver sea hanging in space, the edge area being commonly referred to as its ‘coast’.

Professor Yana was found on the edge of the Silver Devastation, a naked orphan in the storm with nothing except for a strange fob watch (Although it is possible that the Chameleon arch created these memories). (DW: Utopia)
