Master of the Monolith

The Master of the Monolith is a monster from Robert E. Howard's short story "The Black Stone", it was heavily inspired by the works of Lovecraft and is indeed very Lovecraftian in nature. Appearing as a gigantic, hideous toad-like creature the entity was worshipped as a god by a degenerate cult of Romanian origin and was an embodiment of all humanity's most horrible qualities such as greed, lust and malice. Yet its cult worshipped it regardless and conducted many terrible rituals to appease it, sneaking into the lowlands to steal women and children to be sacrificed to the beast. However the monster was put to an end (along with its cult) when Turkish warriors came and conquered the area.
