What is "khemri"

An undead nation in the fictional world of the Warhammer Fantasy setting, Khemri is home to the Tomb Kings, an army composed of skeletons and various decayed creatures. The theme of the army is based on the culture of Ancient Egypt, with an emphasis on its more morbid tendencies such as mummification. Correspondingly, the hordes of skeletons are led by withered liche-priests who used a proto-necromancy/death magic (less potent and sinister than true necromancy practised in the modern Warhammer world) and resurrected kings and princes. Khemri was originally called Nehekhara, of which Khemri was a major city.
