I know the video isn't about that kind of conspiracy, but I find these similarities to esoteric lore fascinating:
Mercator said there is a Black Rock (rupes nigra) at the North Pole that is responsible for compasses pointing north, surrounded by 4 islands and with the water draining into the Earth like a funnel.
Also in the alchemical process of Magnum Opus or Great Work to create the Philosopher's Stone, black rock could be the end product of nigredo. Many alchemists believed that as a first step in the pathway to the philosopher's stone, all alchemical ingredients had to be cleansed and cooked extensively to a uniform black matter. This is also commonly represented by sol niger, the black sun.
That is commonly translated into political thought by homogenizing the whole world. There's the Nazi, Skull&Bones interpetation, burn the whole world until one Volk is left and then there's the peaceful panhumanist interpretation.
I wouldn't be surprised if the name was actually chosen to represent the Nazi black sun, you know how elitists be.
