[Dark Souls] what happens if the fire isn't linked? SPOILERS

SPOILERS 

I read there is a difficult to achieve ending in DS3 where the protagonist doesn't link the fire, but I'm confused on what that means.  What happens to the world if the fire go's out?

The world goes dark, but after a long time, tiny sparks of flame will dance across the dark, implying that the flame will eventually relight itself. There is a different path, where someone powerful enough with "dark" (as in the dark soul) can corrupt the flame, ushering in an age of hollows, where the true form of humanity reigns supreme.
