A diabolic cult of spider worshipers raids villages and cities all across the jungle lands between the great rivers.
They take their captives to feed their god incarnate...
a giant demonic spider. how can this be? The secret is that the high priestesses conjured the monster,
it is under the spell of the high priestess command so long as she maintains the bargain.
The huge spider must eat one person each new moon.
in return the spider gives silk and eggs: the eggs endow the eater fantastic regenerative healing, strength, and speed...
but only for a while. thus eggs are given only on nights of the hunt to the most favored hunters.
in time, those who eat the eggs find their bodies changing - their eyes become compound eyes, they grow chitinous armored skin, a lower jaw that splits open to reveal acid dripping fangs,
claws and barbs gradually replace fingers and toes, they can grow extra limbs, and spinnerets replace their navels, and they too hunger for the flesh of the innocent.
cultists who have changed too much are judged by the spider-god: some are exiled to guard the mountain passes. others are eaten,
and some suffer the worst fate imaginable: mating, which ends with being eaten.
the villagers and the great cities can try to defend themselves as best they can, they do not know when or where an attack will come.
Any new comers to these lands are often captured and delivered up to the cultists in exchange for a season of not being attacked.
the region is isolated, being the bottom of an aeons old meteoric crater over one hundred and twenty miles across and twenty miles deep. tall mountain ranges serve as walls and
the rivers that flow out the southern mouth into a deep underground canyon of lava tubes are guarded by exiled cultists as well.
the people of this jungle land can not escape, neither can any of the other life which had come here so long ago. these lands are rich beyond imagination...
but doom all who would enter there.
