The Third are massively unhappy with their lot, but know not how to improve it beyond staging futile rebellions during the humid and oppressive nights of the wet season. When not rebelling, they find release in breeding. The lot of the slaves is almost beyond despair. They are the men and women who have fallen into such poverty they sell their bodies, wombs and souls to the highest bidder. Their bodies till the gloam plains until they rot and fall apart, their wombs are used by men from the free who need inexpensive bastards to clean their kitchens and stables, their souls are toyed with by the rich until their amusement dies along with the slave.
Slaves live to die, and no-one knows that better than the slaves themselves.
Such is their despair they think not of revolt, but only of the release of the final obliteration. But the figurines are useless until they are given power. Each figurine is empowered by the soul of a man or women. Slaves provide the soul. Once a figurine is finished and purchased, then the buyer must also purchase a soul to inhabit the figurine and give it power.
