Death in the Fifth City isn't necessarily the end. If you're stabbed or shot, someone may come along and sew you back together soon enough. If you're drowned, you'll wake with a hangover. If you die of old age or disease, or if you're hacked to pieces, it's a more serious matter. But in any case, once you die and return to life down here, you'll never be permitted to return to the surface... unless you're one of the few who find a way to immortality.
