Amber (fictional realm)

The fictional realm of Amber is the setting for the Amber fantasy novels by Roger Zelazny (and for the Amber diceless role-playing game game they inspired).

In the Amber stories, Amber and the Courts of Chaos are the only two true worlds; all others, including our Earth, are but "shadows" of the tension between them. Royals of Amber (as well as equivalent Chaos nobility) can freely travel through the shadows and alter them, but they cannot do so to Amber itself.
