Slaanesh

Intro Slaanesh, also known as the "Dark Prince," the "Prince of Pleasure," the "Lord of Excess," the "Perfect Prince," and the "Prince of Chaos" in the Imperium of Man and "She Who Thirsts" among the Aeldari, is the Chaos God of pleasure, pain, hedonism, excess, perfection and decadence. Lust, pride and self-indulgence are the hallmarks of all who follow it. Slaanesh is the youngest of the four major Chaos Gods, having come to full self-awareness within the Immaterium only during the 30th Millennium. 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."
