Sorry for this delayed reply. I missed reading your posting and it’s only now that I got to see it in the discussion board.
Definitely yes, the conjunction “nor” can be used without the conjunction “neither.” On its own, “nor” is used to introduce the second or last member or the second and each following member of a series of items, each of which is negated, as in the sentence “The burden wasn’t carried by you nor me nor by anyone for that matter.”
Of course, when only two members of a series of items are involved, “nor” works with “neither” in the negative correlative form “neither…nor,” as in “Neither you nor me carried the burden.” This construction follows the traditional grammar rule that the negative correlative “neither…nor” should only be used to mean “not one or the other of two.” When the reference is to “none of several,” “none” instead of “neither” is used: “None of the five reelectionists passed the advocacy group’s integrity test.”
Also without the conjunction “neither,” the conjunction “nor” is used to introduce and negate a following clause or phrase in a sentence, as in “The candidate didn’t mind being labeled a family dynast, nor did she mind being deemed unqualified.” On a more profound note, the same stand-alone usage of “nor” is used in Psalm 121:6 of the New International Version of the Bible: “The sun will not harm you by day, nor the moon by night.”
