He was a shape shifter and used that ability to either try to trick Alexander into killing himself, or spy on Alexander. His eyes look like the burning gold of twin candle-flames. He took on the forms of an old man, a swimming boy, a snake, a weasel, a raven, a middle-aged gardener, an old woman, lady Celeste, and even Cassima. He can be recognized by the golden glint in his eye regardless of his shape.
