The Caileach from Irish and Scottland pagan mythology. Also, named Beira, The Queen of Winter and often are the same deity and not two separate ones. As for lore in the series one can play her as the BBC series did in Merlin. A powerful death goddess associated with the spirit world or land of the dead.

"My idea if I could make her this way'' That the Caileach is as old as the Earth and is a powerful pagan god that God left to guard the Land of the Dead or Spirit World. While not a paradise like Heaven it's not Hell either, comparible to just living in an eternal sleep there. The spirit world is where, the majority of humans souls go, that aren't evil enough for Hell or righteous enough for Heaven. As for the plot. She is anger with Sam and Dean for always cheating death and for all the resurrections etc that are associated with them. As, (playing to lore and fandom.) the Earth while isn't center of creation, it is the physical location where veil that separates the physical realm from all the spiritual ones like Heaven is the thinnest.

So now a crazy sorceses not a witch, after she lost a child wants to destroy the veil thus fusing the living world and the spirit world together, to make the world suffer. But to do that, it reguires three things, the Caileach's death, bone from a person that has been buried in the Earth for at least one hundred years, and the blood of a man that has been to Heaven, Purgatory, and Hell for the spell to work. So now the Caileach wants to kill Sam and Dean, to prevent the spell from working, as the man has to be alive before the blood is taken for the spell. As how to kill the Caileach, it is a stake made from an oak tree that grows in a cemetery.

I'll make how she would be as Beira a weather and mother goddes, later.
