Maybe, I shouldn't have made the plot so end of the world. But, I did try my best to follow realistic SP fashion and connecting the series lore with real life lore. Like how the Caileach could be seen as a death god, like how to kill her with an oak tree stake, from an oak tree that grows in a graveyard or cemetery.

As a graveyard is associated with death and she could be seen as the spirit world's gatekeeper, and trees or stakes are a common god killing method. So, I simply drew that conclusion.
