I've come up with a theory about the  supposed retcons about the Do's origin, the Vault and the Darkness. Here goes:

Nimue created the Vault as a hiding place for the Dagger and as an added precaution, created the curse that passed her power, her very essence, onto another. That stuff about being born from the Vault was just a myth created over time. As for the Apprentice,  who knows? Maybe Merlin lied about Nimue's corruption.
