A Human Design Incarnation Cross whose four defining gates all fall within a single quarter of the Mandala, so the Conscious and Unconscious Sun, Earth, and their pair all draw from the same tightly clustered thematic neighborhood. The System treats this as the rarest and most self-contained cross configuration, its life theme concentrated rather than spread across opposing or neighboring quarters. Belongs here: any Incarnation Cross whose four gates sit inside one quarter. Does not belong here: crosses whose gates sit in two opposing quarters, grouped under Right Angle Cross; crosses whose gates sit in two adjacent quarters, grouped under Left Angle Cross.
