The shaperate is very isolated and remote to the rest of the main areas of the underworld. Not entirely unknown, just far away and doesn't interact much with anyone else. Has three moderately sized cities, some research outposts, and a whole lot of wilderness. Wilderness even more dangerous than most given the amount of experiments the shapers let loose to see how they do against each other.
A land where controlled biological mutation is the main form of magic, experiments with life and alchemy are a common event, and sapient life is cheap but exotic feral creatures can be worth their weight in diamonds.
Known specialties: the ability to create and shape life, exotic alchemy
