I think that simply that Nimue's Darkness managed to live on. She performed a spell on t the dagger to allow Darkness to live on. So, all the Darkness stuff is just everyday darkness but collected over a host of people. Only Nimue's Darkness allows the person to have immortality and magic powers, while the others just make the Darkness bigger and swirl-ier.
