"There was a game last month, with a dreidel," the Soldier explains, putting the coin and stone away, letting Sora examine the ruby. "When someone won, they got a prize. Just magically appearing. The rubies were the best one. They stay warm all the time." Perfect for making patrols in a blizzard, right? Also comforting to just hold, even inside, and keeps the worry stone warm if kept in the same pocket. "The gold coins are pretty, but useless here. Nobody needs gold."
