The LEUP is a plague that has taken over the Qafuri. The symptoms are cancer-like: growths on the skin that slowly decomposes the body of the infected person. It is unknown how the disease spreads, which is why it is seen as a curse. Some believe it comes from a certain family that disgraced the God Ata Emit.
Finding a cure for this mysterious disease is the goal of the Hakkinen and everyone in the Qafuri. People have turned to the military for help, while others, such as the Hells, see it as judgment day from the Gods and welcome it. The war in the Qafuri is based around this disease and surviving it.
