Hiro starts walking away from the Street, toward the cube. It reflects no light at all, so he can't tell whether it's ten feet or ten miles away from him until the security daemons begin to materialize. There are half a dozen of them, all big sturdy avatars in blue coveralls, sort of quasimilitary looking, but without rank. They don't need rank because they're all running the same program. They materialize around him in a neat semicircle with a radius of about ten feet, blocking Hiro's way to the cube.
