In our civil war, we’ve seen death. We’ve watched our people die. Gone forever. As terrible as it was beyond the reach of the Resurrection ships, something began to change. We could feel a sense of time, as if each moment held its own significance. We began to realize that for our existence to hold any value, it must end. To live meaningful lives, we must die and not return. The one human flaw that you spend your lifetimes distressing over… Mortality is the one thing… Well, it’s the one thing that makes you whole.
