My world has a society of mages that can only communicate through empathy. They communicate by reading and projecting the "internal voice", effectively deriving their information from telepathic emotional signatures. Each of these mages is raised to do this since their birth. Traditional linguistic skills hamper their magic, so they actively avoid learning them.
There are advantages and disadvantages to this of course. One advantage is that they can effectively understand any other human. All humans feel emotional traces and see related images to our message while we speak, though they can't understand words. For example; they will know if you're lying, but won't know the words you are saying.
Disadvantages: They're completely illiterate and mute. They do possess a special script, but the characters of this script function much more like dynamic calligraphy. The symbols are created such to convey traces of emotion, and have no consistency like one would find in any language on earth. These mages often create entirely new script characters for emotional patterns you or I might attribute to simple nouns, but other mages of this order intuitively understand what these new characters represent.
Our mage is one such character. I want to give him a verbal name but I'm having trouble thinking of a reason mages of this order would assign verbal names. Surely each mage would become identifiable to the others as his actions defined him and his appearance began to finalize, thus giving him a unique emotional signature.
How could a verbal name come to be assigned to a mage of this type?
