-Not many humans have a good education, however, Cillian had the opportunity to apprentice under a fae scholar who would not tolerate a slow student.
-This leads to him teaching others whenever possible, although it is not something the fae would approve of so he never gives his name. And so, many of his students will simply call him 'teacher'.

-Someone called him this once and he just stared them down until they apologized and left the room.
-Pet names or anything like that are just not his thing.

-Between working as a scribe and always scratching off quick but elegant notes on scraps of paper to pass along to others, Cillian finds his fingers to always be stained with ink blotches.
