Who/what has followed the party?

As the party travels, they may pick up a hanger-on or two - perhaps they have gained some notoriety, or some opportunistic individual(s) hope to join for fortune or easy pickings, or just something following you for reasons of its own...  Some may be almost helpful.  Regardless, they're at least one more mouth to feed...
