Xero was an archangel, a figure of galvanic energy and uncertainty. As he moved across the abandoned landscape near the flyover, the very perspectives of the air seemed to invert behind him. At times, when Xero approached the forlorn group sitting on the embankment, his shadows formed bizarre patterns on the concrete, transcripts of cryptic formulae and insoluble dreams. These ideograms, like the hieroglyphs of a race of blind seers, remained on the grey concrete after Xero had gone, the detritus of this terrifying psychic totem.
