Obelisks are mostly placed on earth grid places, where bad influence appear, so the obelisk will pull the energy up and radiate it like an antenna. Through history they were placed by your 3D rulers with occult knowledge about that. Giving them further control to radiate control frequencies right into a city. Officially this is masked as modern art, but it is an instrument of influence. So don’t be wondered if you suddenly see Baal Gateways or Black Obelisks in your city. This is Cologne in Germany, the Obelisks was placed over night like the Georgia Guidestones.
While in Kassel the Obelisk was placed in bright daylight with the excuse to be modern art. But there is no one to blame for that, as long the people denial to look what their rulers really do and are.
The Obelisk and Baal Gates act the same way, when placed on the right places on earth grid. Like an acupuncture placed into your body meridians. To weaponize the earth below your feet against you.
