From Arcanet
Arcanograms refer to magic signage throughout the city. When one focuses on the symbols in an arcanogram, they are granted a subjective understanding of the message without any prior knowledge of the symbol's meaning. These may be shop signs, advertisements, warning signs, maps, schedules, or anything other number of things.
Each citizen has their own personal arcanogram, as do most businesses, which generally have them as signage on the outside of their building. One can visualize an arcanogram when using their ego bracer to contact the owner.
