There may or may not be a vault for Merlin, we still don't know how the vault forms was it created by Nimue? Or was it a natural manifestation of the magic? What we have to consider is Merlin said the complete sword could destroy the magic and leave the host whole. Whereas the dagger could only kill the host, the magic is left intact. There is no difference between Merlin's and The Dark One's magic. If the dagger could kill the host and leave The Dark One's power intact and used as a medium to transfer the power. Also what did you mean that "Excalibur was blank'? The whole blade was blank in the flashback to the forging, but Arthur had Merlin bound to the sword and his name appeared on it. In the still Hook's name has replaced it. It isn't "currently" blank unless you have another image?
