Who is Rix from Sapphique and what is their importance?

Rix is a magician that lives and works in the world of Incarceron. He enlists Attia to help him pull off his magic tricks to convince the audience that he has magic powers. Rix also has a collection of gloves that he keeps on hand. One of the gloves Rix owns is the real glove of Sapphique, so it is a glove that has magical powers.

At certain points in the novel, it seems as if Rix is convinced that he really is Sapphique. Rix also seems quite unstable. There are times during the novel when Attia is not sure if Rix really is crazy or if he is just acting as if he is crazy.

Rix insists on being able to speak to Incarceron face-to-face. Incarceron indulges Rix. While Attia, Keiro and the warden are trying to open the portal to find Finn and reunite the warden with Claudia, Rix is being selfish, so all he cares about is himself and whether or not he can stare Incarceron in its eyes.
