The Lich Gardens is a commune of liches dug deep beneath the soiled earth of the Festering Wastes. It is hidden by way of its entrance being beneath the murky waters of the canyons, as a security measure to ensure the entry of only those who are not required to breathe.
In the underground garden, artificial plants are grown, and mindless Undead are imported in large number as test subjects for the colony's cruel experiments. The ultimate goal of the scientists, is to create a method of strengthening Undead kind by way of turning those who were forced into undeath - the mindless - into functioning, intelligent followers. In their quest they also look for the means of turning the wilderness itself into undeath.
