‘We follow the Xeelee,’ the Ghost said laconically. ‘As I said. We watch them. When the Xeelee which you wounded, Michael Poole, began building a significant artefact at the centre of our Galaxy, we came to study it. We believe that this Xeelee, unable perhaps to reach the Great Attractor in this epoch – and certainly unable to contribute to the dark-matter war – is seeking to survive by accelerating through time. Thus it inhabits the extreme dilation zone, down on the lowest levels of the Wheel.’
‘Ah,’ Poole said. ‘Only a few months subjective, five million years objective.’
