Juddarith, a human necromancer in the city of Qarathas in Eastern Rasharan tried to raise an army of undead and gain control of the city. She was put to death and her rebellion was put down, but she had enacted the rituals to become a lich long before.
Over time, the lich allied with genies from the Elemental Plane of Earth. Catching Qarathas unprepared, the lich and her armies razed Qarathas and the human settlements in Eastern Rasharan, submerging the land in deep sand. Calling herself the Sandsower, she advanced westward, but was halted by the combined might of the halflings in Western Rasharan and the surviving humans who fled west. With her phylactery destroyed, the Sandsower War was ended and the surviving genies retreated to Eastern Rasharan.
