The taes symbol language differs from mapmarks and similar pictographs in that it straddles the area between read and pictured images. It is separate from map marks, and typically does not appear on map legends, since it is a well-established cartographical shorthand.

Though taes-whits originated in the mid-1400s around the area that would become the city-state of Brilliance, it has since spread nearly to the borders of Eluthisura. The only area that still produces maps while staunchly refusing to incorporate taes-whits is the traditionalist religious compound of Lora-Quielle.
