[Pet Sematary] so what is the mechanism by which the Micmac burial ground works? How did it sour?

Was it created by some sort of spell, or did it always exist?

Are the reanimated bodies inhabited by a soul that was summoned into them by the ground?

What caused the burial ground to "sour"?

How sapient are the revenants after being brought back?

How far does its influence actually extend?

Thanks!

The ground became sour after the indians dug up remains to eat during a very long winter in which they were starving. They were thus touched and cursed by the Wendigo spirit and that burial ground became a cursed an evil place with a will of its own. The Wendigo still roams those parts, you can hear his laugh as you make your way to the cemetery.

The influence of the burial ground extends extremely far..... it made it so that his wife Rachel couldn't make it back home from Chicago to Maine in a number of ways.

Those who come back are not, in any way , shape or form, those who left. The being has their memories and will use them to inflict pain and suffering to everyone around, but it's not them.

The reanimated bodies are inhabited not by souls, but by evil spirits of nature. Devils, demons, pick your term.
