Hastur (Lovecraft)

Hastur is one of the many Cthulhu Mythos deities, acting as one of the most mysterious of Lovecrafitian gods. First appearing in Ambrose Bierce's Haita the Shepherd, the god has been stated to be Cthulhu's half brother, a fallen angel, the god of shepherds, and the duke of Hell itself.

Appearance
Hastur's true form shall never be revealed, but there are two main ways that he is constantly imagined. The first one is a shapeless blob of octopi-like appendages, a common trait among Cthulhu related deities (and is also similar to his half niece Cthylla). The second is a humanoid hidden by a golden cloak with a family of similarly colored tentacles oozing out from under him.
