Rhogog was said to be created when Cthulhu and Hastur fought above the British Isles and Cthulhu shed blood, which several Star-Spawn put an 'entity' into for unknown purposes. This 'entity' lay dormant, growing in power until it became Rhogog. Rhogog is a great, black oak tree, hot to the touch, and a being of darkness, and unimaginable power.
