[General fantasy] What happens if the god of death dies or is killed?

e.g. Thor kills Hel, or Hercules defeats Hades - do they then replace them as the respective god of death? Does everything just sort itself out? Is a new god just created to replace them?

What would happen to all of the souls from the departed? Do they just drift in some limbo-like ashen wasteland for eternity? Or do they just fade into nothingness?

It's not precisely the same, but there is an entertaining series of novels within the Discworld series about if Death decided to go and find the meaning of life, or fill in for Santa Claus, or just plain take a holiday. In most cases, Death's granddaughter, Susan, takes up the reins.
