Ithaqua is one of the Great Old Ones and appears as a horrifying giant with a roughly human shape and glowing red eyes. He has been reported from as far north as the Arctic to the Sub-Arctic, where Native Americans first encountered him. He is believed to prowl the Arctic waste, hunting down unwary travelers and slaying them in a gruesome fashion. He is believed to have inspired the Native American legend of the Wendigo and possibly the Yeti.
