It doesn't.

Gradually you realsie that fate isn't going to intervene any time soon. You pass the time by doing what you did before, sleeping, but as a creature of undeath you feel almost restless at being so close to your tormentor but unable to do anything.

Eventually she sells you to a local merchent for 10 copper pieces, its a bit of a slap in your jawless face that you are considered so worthless but its just another cross for you to bear.

Its quiter in the merchants inventory. There's no sound of battle but heroes are always coming in and out of the shop keeping you awake.

Some time later you are bought by a witch who uses you as a table decoration in her house. Its not a bad existance, she's never home so you get the rest you so desperately wanted and you one once got to see her in her underwear. So you sit, a jawless skull on a table for all of eternity, or at least until the hero stops paying their subscription and their account is deleted.
