The living do not see eternity, just as they don't see Everlost, but they sense both in ways that they don't even know. They don't feel the Everlost barrier set across the Mississippi River, and yet no one had ever dared to draw city boundaries that straddle both sides of its waters. The living do not see Afterlights, and yet everyone has had times when they've felt a presence near them - sometimes comforting, sometimes not - but always strong enough to make one turn around and look over one's shoulder.
