Qui-Gon called the boy from Tatooine a vergence. Temples are built on them. Caves show you the face you brought. Mortis is one that is not on the map. A vergence is not a loot crate. It is a concentration: light, dark, or neither. The chart is the geography. This plaque is the word.
Standing in one does not make you the Chosen One. Anakin already was. The cave on Dagobah still showed Luke himself.
