Mannslieb is a white-grey lump of cold rock which affects the tides of the Warhammer World; it is seen as very similar in appearance and size to Earth's own moon, Luna. Mannslieb is a word in Old Reikspiel which means "Beloved of Manann", a name earned due to Mannslieb's having an effect on the oceans' tides (Manann is the Old World god of the sea) similar to that possessed by the Earth's moon. Mannslieb is known to the Dwarfs as Gormlhune - roughly translated into Reikspiel as High-Moon, or Old-Moon.
