At the end of my musings on the first few chapters of Nine Princes in Amber last week, I opined that much of the setting, or at least enough to get a handle on, would soon be explained. As we shall see, I was more or less correct.
As I suspected, Corwin's memory was soon to be returned, but not without a good bit of effort. After meeting up with one of his many brothers and discreetly dealing with the pursuers thereof, the two decide to make the journey to Amber. In a situation not unlike the Pevensies hearing the word "Aslan" for the first time, the word "Amber" conjures up in Corwin a host of associations - he doesn't know what it means, only that he belongs there.
The journey itself is an interesting affair, consisting of what seems to be a number of jumps between alternate universes. Random, the brother, is controlling it somehow, and the travelers' effects change somewhat along with the surroundings (at one point Corwin pulls a bunch of paper currency labeled in Latin out of his wallet), although he isn't able to route them around all the obstacles, including a chase scene with another brother - this one a knight with a pack of especially ferocious hunting dogs.
Corwin takes all this in stride despite his lack of memory, which he eventually confesses to Random. Happily, a solution is offered - a powerful labyrinth called the Pattern that, when navigated by a member of their family, gives their various powers and should restore Corwin's memory. Of course his labyrinth is in Amber itself, but luckily there's a duplicate located at the bottom of a nearby ocean.
Of course it works and Corwin remembers not only his activities for the past several centuries, but the true nature of Amber - ". . . the greatest city that had ever existed or ever would exist. Amber had always been and would always be, and every other city everywhere, every other city that existed was but a reflection of a shadow of some phase of Amber." Heady stuff, and an interesting reversal of the usual assumption that our Earth is the "real" one. It's also, come to think of it, again not unlike the situation in Narnia, where the world the bulk of the stories take place in turns out to be a transient copy of somewhere more real.
Unfortunately for Corwin, however, now that he remembers what Amber is he also remembers that yet another brother - this one a particular rival - is poised to take control of it. Whether Corwin succeeds in stopping him, however, will have to wait for another week.
