Description: A rock formation that, upon closer examination, proves to be a truncated three-sided pyramid. While the visitor watches, a vignette plays out that links this place with 12 others scattered at regular intervals around the Island, which, taken together, reveals a pattern and the place's backstory as well as that of Gi Normus.
