I've worked up a fantasy world that has (among other things) four races often hired as henchmen or lackeys. Their cultures were progressing pretty well except for one. I wanted to make one of them 'unnatural' or eldritch so, long story short, they basically poof into existence in dark places, such as caves, deep forests, poorly lit wine cellars, etc. (Although there is a heated philosophical debate over whether they indeed 'poof' into existence or if it is more of a 'pauf', or perhaps 'boof')
Anyways, they start out with enough knowledge to survive until they get to civilization, they can use some magic, and they have a few natural defenses to ward off hungry animals, namely a reeeeaaaally creepy/unnatural aura around them that drives animals away (although they grow out of that after a while).
My problem is this: If they don't have children, heritage, or family in general, or . . . anything of that sort, what is their culture like? Would they even have a culture? Or a society, or traditions, or superstitions, or any of that fun stuff?
