'But, as you say, Luru Parz, the Xeelee are different. These spacetime defects of which they have been baked aren't common at all. Or at least, not now... but there was a time in the universe's complicated history when they were common. The Xeelee—or their progenitors—must surely have arisen in an earlier age of the universe, an epoch when spacetime defects proliferated. But that era was in the first moments after the singularity. If that's true, the Xeelee have very deep roots in time.'
