There is not only one Barrow-wight. They are spirits and wraiths of Angmar. I do not think the quote has to do with Melkor and the Dagor Dagorath, but rather with Sauron if he should gain dominion over Middle-earth. The "dark lord" it refers to is almost definitely Sauron, although I am sure that if Morgoth returned the Barrow-wights would happily follow his command.
