"I seek neither heaven or hell
"but the Earth between to be well
"So I ask to be granted new life
"And I hope to forever escape strife."
You recite the incantation the Grim Reaper taught you, then suddenly the gate to the afterlife vanishes leaving you in the darkness. A glyph appears on the ground beneath you and glows an alternating colored light. The light shoots up from the glyph and circles around your body. Your clothing vanishes, leaving you exposed were there anyone here to see. Then the glyph seems to be getting closer to your face. Then you realize, you're getting smaller, younger. You look over the parts of your body as you watch years added to your life reverse themselves. Your limbs become thinner, and you're of course much shorter. However, you expect as you get younger you'd have less body hair, however you seem to be growing more. Red hair erupts all over your younger body and thickens, until you have a coat of fur over your entire body. Then, you feel something snake out from where your tail-bone ends. You turn your head just in time to see a fluffy red furred tail with a white tip grow from behind you. A fox tail. As you take that in, you feel your ears tingle. You can't see them, but you reach a hand up, and can feel them become pointed, and move to the top of your head. They too are covered in fur. Your eyes unfocused for a moment, as the tip of your face pushes out into a muzzle. Then, you feel a sharp twang in your hands and feet. Your feet elongate, and resemble paws. Your hands are in a similar condition, but remain human enough for you to still have fingers, and thumbs.
The light retreats from the glyph and your body stops changing. You take a look over yourself, and come to the conclusion that your current age is around 12, and that you're an anthropomorphic fox.
Then, the glyph on the floor fades, and the darkness retreats. You find yourself now standing in the middle of a clearing in the forest. It appears to be apart dawn, and you see no one else anywhere close by.
