Psychosis

A light dragon is many things, but above all they can most easily be defined as inquisitive and scholarly. They revel in the concept of learning new things and exploring the unknown and Psychosis is no exception. She took a particular interest in thought and matters of the mind. Unfortunately most light dragons are also held back in their search for knowledge by a trivial thing called ethics.
Psychosis runs experiments on the minds of dragons in a variety of ways. Tests for how much pain they can feel, how intensely they can express emotions, what certain herbs and medicines do their cognitive processes. Her research has only produced three times as many victims as cures.
Either way her experience makes a good psychiatrist, (assuming she doesn't get too curious.) and a decent healer, which has resulted in her employment by Reflet. She keeps all of his workers and den mates in working condition, and he provides her with materials, test subjects, and a place to stay.
