The jolly fat man whose belly shakes like a bowl of jelly brings the native peoples of La Hispaniola some memorable gifts that fuzzy Christmas of 1492.  How about some 30-odd swarthy, horny, heavily-armed Spaniards and a virulent disease to which you have no microbial resistance!  The seeds of conflict are planted as 1492 passes into 1493, and Columbus returns (heavily reinforced!) to find a bunch of ruins, some Spanish bodies and no gold at all.  What would Jesus do?
