Heads or Tails
Morrslieb, also called the Dark Moon, is a giant black and green lump of rock that erratically orbits the Warhammer World. Morrslieb is seen as a symbol of Chaos and unvarnished evil to many of the inhabitants of the Warhammer World. Morrslieb has eclipsed Mannslieb several times during the history of the Warhammer World, an event that always heralds dark times.
Morrslieb is said to be made from a giant chunk of Warpstone, though obviously this is unable to be verified. In the Warhammer World, the Skaven, an intelligent race of rat-men, are notoriously fond of Warpstone, large chunkc of which have been known to rain down on the Warhammer World from the skies.
Morrslieb’s name translates from Old Reikspiel as “Beloved of Morr”, the Old World’s god of the dead, and there are a great many myths and legends that explain the Dark Moon’s nature. However the deity Morr, unlike the moon Morrslieb named for him, is not associated at all with Chaos or evil, but rather the ending of life (regardless of the manner in which it is achieved) as well as dreams and portents.
Where Mannslieb is full every 25 days, on a constant and predictable cycle, Morrslieb is not. Indeed, few have been able to accurately predict Morrslieb’s cycle, and the moon’s appearance varies from night to night, sometimes appearing nearer the world, sometimes further away – it has been speculated by Imperial scholars that it appears differently when viewed from different locations, such that a man perceiving it as full over Altdorf would see it waning were he in Talabheim.
In spite of this arcane irregularity, there are only two nights where both Morrslieb and Mannslieb are full during the year: Witching Night (the first day of the year, also known as Hexensnacht in Old Reiksiel, or Hekesdrazh to the Dwarfs ), and the Night of Mysteries (exactly 6 months later, about a month after the Summer Solstice – also known as Geheimnisnacht in Old Reikspiel, or Skraksdrazh to the Dwarfs).
The Dwarfs know Morrslieb as Mhornalhune – translated roughly into Reikspiel as “Shadow-Moon”.
