For some reason they're in my campaign "more than ever." I'm sure it's not deliberate or part of an unconcious fetish, but I am using more "Hobbits" than ever before. I follow the traditional fluff that halflings are hobbits - short, plump, and jolly. However, I also follow the idea that they can be devious and wicked. For example, in my campaign the players were just attacked by a group of halfling highwaymen. They were pelted with stones, stabbed, and poisoned. Eventually they the PC's started getting the better of them and the halflings ran and hid in some caves but not before causing some serious lumps.
