Ithaqua is an Ancient One that appears in the Elder Sign Core Set and Omens of Ice, an Epic Monster that appears in the Eldritch Horror Mountains of Madness, and a Character Card that appears in the Call of Cthulhu: The Card Game Forgotten Cities.
Ithaqua first appeared in the story The Thing that Walked on the Wind (August Derleth, 1933).
Ithaqua is a Great Old One and its domain includes most of the northern regions of Earth. Ithaqua appears as a tremendous anthropomorphic shape with glowing red eyes and webbed feet that walks through the air as if on solid ground, or as a cloud of mist or snow with eyes. The Wendigo often emits eerie howling noises, but seeing the creature is worse; any that gaze upon Ithaqua are doomed to be taken by him.
Like many of his fellow Great Old Ones, Ithaqua seems to be limited or imprisoned in a certain area. It originally rested beneath a plateau on the world of Borea, until it was able to escape. On our own planet, Ithaqua is unable to leave the area between North Manitoba and the North Pole, though in certain circumstances the Wind-Walker may travel further into temperate climates. Those in warmer latitudes who consider themselves safe from the Wind-Walker's wrath should beware, however; the Arctic boundaries do not constrain the servitor winds and other minions of Ithaqua, who may be sent anywhere in the world at their master's command.
In the north where his true nature is known, Ithaqua is more widely feared than worshiped, and most of his cults died out in the early 19th century. Centers of this cult existed in the town of Stillwater, Manitoba, the inhabitants of which all vanished in the space of one night, and Cold Harbor, Alaska.
