Ego and Id: The two gloves created from the ancient essence of the First Spirit of Magic allow Faden to manipulate Desire and Will directly, as though the abstract concepts were solid to the touch. The actual effect of this is to enhance his magic-based abilities.
The gloves retain a vague, lingering awareness that Faden is not their original owner, and that they were separated through trickery - and they resent it. While they cannot interfere with Faden's use of them, the gloves have the curious effect of leaving afterimages of themselves in the air while they are in use, a sign of their reluctance to aid the son of Baz'Auran.
Contrary to popular belief, one glove is not called Ego and the other Id, they are both Ego and Id.

The final attack of Qarezel and Paideiazel ripped the flesh from Faden's bones, scattered the bones, incinerated all of the aforementioned pieces and then vaporized what was left. In short, nothing of Faden's original body remains.
Faden's new body appears to be a wrapped burial shroud in the general shape of a male humanoid. However, external features such as a nose, mouth, ears, etc. appear to be missing - fingers and eyes are the only true detail, the rest is merely jet black ribbons wrapped tightly around something. Faden's eyes are the only gaps in the ribbon, and looking into those reveals only a burning blue-white light. Faden's clothes remained, and are almost always worn over the shroud ribbon. Only Faden's face - such as it is - is visible, the rest being covered by boots, pants, a tunic, a belt, a split black jerkin, and the blue, black, and gold hooded robe - and of course, Ego and Id.
