For ArtOrders HP Lovecraft contest due today. It's a Shantak.
"They were not any birds or bats known elsewhere on earth or in dreamland, for they were larger than elephants and had heads like a horse's. Carter knew that they must be the shantak-birds of ill rumour, and wondered no more what evil guardians and nameless sentinels made men avoid the boreal rock desert."
—H. P. Lovecraft, The Dream-Quest of Unknown Kadath
