Chocolate Milk had come from a place called the trading center, where wolves would trade off their things for silver cones. Sometimes those things included wolves. Chocolate Milk was bought by Prim, and she introduced him to Polly, whom he fell in love with and they mated. Their first litter of pups brought excellent prosperity and lots of promised good, Sepia, Honey, Rain and Frost.
Unfortunately, Frost would be long gone, for he left the pack in low spirits, and having been in a grouchy mood and cranky to anyone around him.
