Ithaqua (the Wind-Walker or the Wendigo) is a fictional character in the Cthulhu Mythos of H. P. Lovecraft. The titular creature debuted in August Derleth's short story "Ithaqua", which was based on Algernon Blackwood's tale "The Wendigo". It controls snow, ice and cold, and can walk through the sky as easily as it walks on earth. Derleth was inspired by Blackwood's tale (who himself based the Wendigo on a creature from Native American Indian legend), but gave the creature a Lovecraftian name.
