The Dark Muses are a group of infamous Dark Eldar who now serve as both examples to aspire to and objects of reverence for their foul race. As far as the Dark Eldar are concerned, the Eldar Gods died in theFall of the Eldar and they despise them for it. That the Gods had become so weak that they could be consumed by the ascendancy of Slaanesh indicates that they never deserved to exist in the first place. The exceptions are Khaela Mensha Khaine, the Eldar God of War who is still held in high regard in Commorragh and the lesser powers known as the Dark Muses who are the embodiments of selfish vice and whose clandestine worship by the ancient Eldar Pleasure Cults contributed to the demise of the Eldar Gods.
The Dark Muses are truly powerful Dark Eldar from ages past who have essentially become folkloric figures of reverence, much like the Imperial Cult's saints. Many epitomise a particular form of vice, whose worship and practice weakened the Eldar Gods and so helped to bring about the Fall. Favoured by assassins and murderers is the Dark Muse Shaimesh, the Lord of Poisons, the treacherous brother of Saim-Hann the Cosmic Serpent. The courtesan elite of the Cult of Lhamaea pay homage to Lhilitu, the Consort of the Void, whereas powerful Archons are more likely to follow the tenets of Vileth, a being synonymous with the immense arrogance so often displayed by the Dark Eldar. Before they enter combat, many traditionalist Wych Cults invoke the Red Crone Hekatii, or make sacrifices to Qa'leh, Mistress of Blades. It is believed by many Dark Eldar that their current Supreme Overlord, Asdrubael Vect of the Kabal of the Dark Heart, may one day join the ranks of the Dark Muses, though given his ability to cheat death again and again, this may be an honour long in the coming.
