The name Slaanesh is a corruption of the Aeldari term Slaaneth ( Slaa meaning 'ecstasy' or 'pleasure' and Neth meaning 'lord' or 'prince' in the Aeldari Lexicon hence, the Prince of Pleasure), though ironically, the Aeldari refer to this foul entity only as Sai'lanthresh, 'She Who Thirsts.' Its sacred number is six and the colours associated with Slaanesh are purple, pink and black.
Slaanesh can assume any physical form male, female, both at the same time or no gender at all, but it prefers male bodies. Slaanesh typically appears in an androgynous form in which it is a woman on the right side and a man on the left with two sets of devilish horns growing from its head. While generally referred to as a 'he' by Humans and as a female by the Aeldari, Slaanesh is actually neither gender, combining characteristics of both and perfecting them. Slaanesh is the youngest of the four major Chaos Gods, having come to full sentience within the Immaterium only during the 30th Millennium. Lust, pride and self-indulgence are the hallmarks of all who follow it.
Slaanesh, also known as the Dark Prince, the Prince of Pleasure, the Lord of Excess, the Perfect Prince, and even the Prince of Chaos in the Imperium of Man, is the Chaos God of pleasure, excess and decadence.
