In the psOne game, The Legend of Dragoon, the main character, Dart has a memento from his father (who is missing) which turns out to be a powerful stone that gives him the power to become a dragoon (a winged knight with the power of fire). Ever since playing that game, I have always liked the idea of mementos that serve as a symbol in the story. In my own novel, I want my main character to have a memento/keepsake from his mother, who is also missing. The item may or may not link to the main character's backstory. I am wondering what kinds of items make good keepsakes and serve as good reminders? Does anyone have any recommendations?
