Slaanesh

Slaanesh is the Dark God of excess, pleasure and pain, the youngest of the four Ruinous Powers, born in early M31 at the peak of the Fall of the Eldar. At the Cleansing of Laeran the Emperor’s Children exterminated the xenos Laer, and Fulgrim acquired the daemon blade of Slaanesh that began his corruption; the composer Bequa Kynska wrote an infected symphony, “Maraviglia”, that gave rise to the first Noise Marines. Slaanesh also lays claim to the traitor House Devine.
