They are always with us, the people of other eras that exist alongside our own, quietly watching the new psyche of the city take form as the world that they inhabited is redrawn, torn down, reclaimed and redeveloped. Their presence is fainter, less vociferous than it was when the city was theirs, but they shadow it, and feed into it … There are lives and spirits and maps and boundaries that they follow which newcomers cannot see.
