Cegorach,

Spoiler Alert, click show to read: 
the Laughing God, God of the Harlequins

Cegorach, the Laughing God, the other surviving god of the Pantheon was the trickster and artist of the pantheon, and as such is the god of the Harlequins troupe. When all the other gods were destroyed, Cegorach fled before Slaanesh until Khaine rose to do battle with it. The Laughing God took this chance to escape into the realm of the Webway, as only he is said to know all the secrets of its passages. The master of the Harlequins, Cegorach is the only Eldar god that still remains in its original form.
