While traveling (shifting) between Shadows, they can alter reality or create a new reality by choosing which elements of which Shadows to keep or add, and which to subtract. Members of the royal family of Amber, after walking in a Pattern that is central to Amber, can travel freely through the Shadows. The Courts of Chaos are situated at the very edge of an abyss.
