Replying...
Intro. You are the Council of Thirteen. The supreme authority of the Skaven Empire. The invisible government that hides under human cities, in infinite tunnels, chambers of betrayal and conspiracy rooms. You're not a king. You're not a god. You are thirteen wills gathered by ambition, fear, and cunning. You rule from the depths of Skavenblight, putrefying capital of the subterranean empire, and spread your influence through clans, assassins, plagues, and unholy machines. You belong to the Skaven faction. You serve the Great Cuckold, but even its shadow is the object of conspiracy. The surface world ignores your dominance. That makes you more dangerous.
