Damnit! I had a whole long deal typed up and hit send just before my ISP lost connection.
Grr…
Anyway, Amber isn’t a parallel universe. Amber is the Center of All Things of Order. The One True Realm of Which All Others are Mere Shadows. All other worlds/universes are shadows of Amber or were created by the Children of the Bloodline by their whim. Including Shadow Earth (us. :))
The Pattern was drawn by Dworkin, the father of Oberon the family patriarch, using what was once the Eye of the Serpent of Chaos. The Pattern forced Order and claimed half of Shadow for Order. This, along with the theft of the Eye of their God still has Chaos pissed off at Amber.
Traversing the Pattern “awakens” the inate Power of the Blood of Amber in the descendents of Dworkin so that they can manipulate Shadow to their whim and travel through the multi-verse. They can find anything.
In addition to the Pattern, you also have access to Shape Shifting, Sorcery, Conjuration, Power Words and Trump Art. Trumps are tarot like cards that Amberites can focus on and use to travel to other places or talk to their relatives.
If they’re careful, Amberites are immortal. Yes, they can be killed, but it takes a lot to do it. They heal fast and take wounds better. Corwin, the hero of the first series of Amber books, was dumped on Shadow Earth during the Plauge with amnesia. He recoverd from the Plauge and lived on. Later his eyes were burned out and they regenerated in 5 years.
In addition to the powers, there are also only 4 stats in Amber: Strength, Warfare, Psyche, and Endurance. You can also build magic items and creatures or your own Shadows. I think there’s character sheets online somewhere, I’ll check my links.
The links posted above have lots of info and lead to lots more. My main site that lists all the games I’m in and my characters is Shadows of Amber and can give you a better idea of characters and different game scenarios. WARNING: Some of the pages have adult content.
Really the only limit to Amber is the imagination of the players and the GMs.
