Frenci is the daughter of the leader of the Southern Night-Gaunts. She is also the former fiancée of Xylo before he became a penal hero. Although Xylo insists their engagement is no longer possible due to his status, Frenci refuses to acknowledge that they are no longer engaged and will not break it.

She has a sharp tongue despite her blank, mask-like expression. A common trait of the Night-Gaunts is that their expressions were still and that altering one's expression is considered rude. The higher social status you are in, the stricter they are when controlling them.
