Deck of Cards - Belongs to Mercury. Quite simply, this is how he wins whenever he doesn't feel like playing straight. The cards can be anything he wants them to be - including the winning hand.
Frakir - She is now gracing the wrist of Niobe, Merlin's niece.
Grayswandir - Corwin is still the bearer of his unique blade.
Motorcycle - It belongs to Kessalia, Benedict's daughter. She is determined that, one day, she will ride it into Amber under its own power. No matter what. No one feels like arguing. Chet recently gave her a bio-engine to install.
Soulsinger - Another Pattern Blade, of the same type as Grayswandir, and carried by Ellyn, Corwin's daughter.
Spikards - Nine of these powerful rings have been located; whether or not there are more is still under debate.
Trumps - Okay, we probably all know what Trumps are, right? So just go here.
Werewindle - In the hands of Rinaldo, and likely to stay there.
