First o all, there ain’t just one, and they ain’t just for Christmas, as anybody who knows about that whole “Paraphenelia Wagon” can tell. Secondly, their actual species name is Green Faces, at least a rough translation.
They’re sorta brought by the wind like those balloon spiders as babies, all wrapped up in baskets, but in the middle of nowhere. They’ve got a knack for tech and a bitter streak a mile wide thanks to knowin nobody for most o their lives.
From what I can tell, the most plausible theory on where they came from is this one city, this big loopy techno-paradise whose intabitants all killed themselves when it turned itno a nightmare. It makes ‘em, at least I think, to create something to share the bitterness it’s left with.
