Chaugnar Faughn
From Tatters of the King

The 'elephant-headed god of Tsang', Chaugnar Faughn is an obscure legend known to only a very few occultists.
He is said to be an unthinkably ancient being that has the appearance of a great statue whose features are that of a hideously distorted elephant, and that he is almost always immobile, waking very rarely to feed on human sacrifices.
The Hindu God Ganesha may be based upon legends of Chaugnar Faughn. Served by creatures called the Miri Nigri, whose nature is nevr described, Chaugnar Faughn is said to inhabit a plce called Tsang where he awaits someone or something called The White Acolyte.
