I didn't see a thread about this article yet, but the newest in the Demonomicon series was released yesterday and if I'm not mistaken, this is the first demon lord that had not appeared in an earlier edition. Codricuhn was a primordial who fell in with the Chained God and after his divine patron's defeat, he was cast into the Abyss and became corrupted by the shard of evil (all in all, its kind of a tragic story). Codricuhn and his exarch, the Voice, and described in digustingly vivid detail, as is his rather unique realm. A very interesting article.
