From publisher blurb:
This is a big fantasy setting for FATE, which has been invaded by the terrible nasties of the Cthulhu Mythos. The game includes a fantasy continent, divided into realms. These realms include human city states, elven forest kingdoms, halfling mounds and dwarven halls, and they are all in imminent danger of what happens when the stars align and the gates have been opened.
This distinctive background, with a high-fantasy feel, integrates beautifully with the cosmic horror of the Cthulhu Mythos. Send your players out against Mighty Cthulhu himself with just a sword to protect themselves.
This PDF includes everything needed to start playing, with character creation rules, a bestiary, descriptions of realms, gear, a synopsis of the FATE Core rules tailored for cosmic horror, and some gritty detail on the advantages and disadvantages of various weapons and armor.
So start exploring this fantasy version of Cthulhu.
