Liber Castellorum lists exactly one tether to light. A bridge between Earth and Lucifer’s original Word located at the point where light first hit the surface of the Earth.
This tether was placed somewhere in Canada, the exact location a mystery… until now.
This past March, scientists found a patch of the Earth’s original crust along Hudson Bay in Nunavik, Quebec. You can read the PBS report on the find (just be warned, there will be no In Nomine references).
