Simply because content within the openings doesn't happen doesn't mean it that does not refer to anything. It was used first by Raven when she was introduced but introduced first itself long before. In the vortex's introduction it seemed to symbolize loomimg evil (team RWBY surrounded by grimm).

Yes it was used when absorbing the maiden powers but as I pointed out it was also appeared as the Salem glove was used and a grimm summoned. Raven is such a mystery that she can't swing it either way and as it was first shown around the time Salem was around (ep 1 narrator) before the maidens even existed as a concept, im inclined to believe it is not associated with the maidens.
