It does look as though the sun is rising somewhere in the middle of the Rock Star Quadrant. Above the heads of the milling avatars, Hiro can see a fan of orange beams radiating outward from some point in the middle of the crowd. It keeps moving, turning around, shaking from side to side, and the whole universe seems to move with it. On the Street, the full radiance of Sushi K's Rising Sun hairdo is suppressed by the height and width regulations. But Da5id allows free expression inside The Black Sun, so the orange rays extend all the way to the property lines.
