The expanding Amberverse from dkap-amber
The Courts have a sort of equivalent [to the Pattern] called the Logrus. It’s a kind of chaotic maze. Keeps shifting about. Very dangerous. Unbalances you mentally, too, for a time. No fun.
The Logrus actually alters itself, constantly. Still, it’s more angular, while Corwin’s Pattern is mostly curves and bends.
It’s thought by some that other Slices of Fruit are available via the (in)correct walking of the Logrus. Not only is this dangerous from a walking of the Logrus point of view, but also from the unknowns at the destination.
