She’d been tutored about this. The priests guarding the gates had enough Breath to get them to the First Heightening, the state at which a person gained the ability to distinguish levels of Breath in other people. Vivenna had it too. It wasn’t that auras or colors looked different to her. In fact, the ability to distinguish Breath was similar to the perfect pitch she had gained. Other people heard the same sounds she did, she just had the ability to pick them apart.

She saw how close a person had to get to one of the priests before the colors increased, and she saw exactly how much more colorful those hues became. This information let her know instinctively that each of the priests was of the First Heightening. Parlin had one Breath. The ordinary citizens, who had to present papers to gain entrance to the court, also each had only one Breath. She could tell how strong that Breath was, and if the person was sick or not.
