Ren stayed in the Undergrid. He still guided the ones who fell through. Sometimes, late at night, he climbed to places where the rain came down through broken grates and looked up at the corporate towers. They still did not see him. He no longer needed them to. New doors had been locked. But in the Undergrid, locked doors were only invitations for someone patient enough to learn the right way to knock. And the city, as always, did not notice. It never did.
