uh, this is probably late, but oh well. the picture is kinda metephorical, from the dragons body comes the ice and from the angels wings comes the snow. the winter dragon has a sister, called the spring dragon. at first they chased each other in a game of tag, but as the time grew, the game of tag turned to a chase. a chase of life or death. now they both chase each other around the world, each seeking to destroy the other, but for now they havn't caught one another, and this is what keeps the balance.
