When Hiro wrote The Black Sun's sword-fighting algorithms—code that was later picked up and adopted by the entire Metaverse—he discovered that there was no good way to handle the aftermath. Avatars are not supposed to die. Not supposed to fall apart. The creators of the Metaverse had not been morbid enough to foresee a demand for this kind of thing. But the whole point of a sword fight is to cut someone up and kill them. So Hiro had to kludge something together, in order that the Metaverse would not, over time, become littered with inert, dismembered avatars that never decayed.
