Spirits of the Fade
According to the Chantry, the spirits of the Fade are the first children of the Maker. He turned his back on them because they lacked a soul -- they could twist the Fade to their liking, but lacked the ability to imagine and create and thus emulate their creator. The Maker created a new realm, seperated from the Fade by the Veil, and this realm would be one that his new children could not alter at will. These new children had the spark of the divine within them, and the Maker was pleased.

But the Maker's first children were jealous. They called out to the mortals, drawing their sleeping minds across the veil and saw the land that the Maker had created for them in their dreams. They coveted the spark within them, but did not understand it. They shape the Fade to create the land that they see in the minds of men, and seek to draw the spark from them without truly understanding where it might actually come from.

Demons are one name for destructive spirits from the Fade. They possess the minds of mortals when they dream, twisting the mortal into an Abomination.
