Have forgotten when Killian challenged Rumple to a dual, he struck the former dark one and got some of his blood? his blood was a key to opening a gateway to underworld and that is how the dark ones got to Storybrooke.

So clearly it makes sense the whole time. That's just what all the dark ones wanted. Follow carefully and harder if you watch it again. The Darkness is just the essence of all the previous Dark Ones.

When Emma stole Merlin's immortality to turn Hook into a Dark One, she made it impossible to destroy the Darkness without resurrecting the previous Dark Ones. Honestly, it was probably the only reason she was to fool Nimue, for so long. I would say that the "Darkness"goop is actually the Holy grail magic/immortality. Emma could still destroy the Darkness by using the sword to take it away from Hook and Herself and still destroy it. Emma's plan was solid.

Nimue broke the sword because MErlin could use it to destroy his and her HG magic.
