Rising high from the center of the sunken pit, the pure white obelisk stands starkly against the sky, made from some strange material that defies any weathering or vandalism. Each of its four corners points exactly in a cardinal direction. The northeastern face is visible here, and numerous markings that represent celestial sigils cover its surface, each one filled with the powder of semi-precious gemstones.
