Whoever meets Cthupheen will never forget this encounter for the rest of his life. The gigantic earthen worm measures many hundreds of steps, its mouth emblazoned with thousands of teeth like those of the shark. Even though his companions, Ijothu and Shoggu Hai, are much smaller, they are still several steps long and half a step in diameter. The black worms are considered death from the earth and devour or strangle their victims.
According to legend, Cthupheen once took human form and fathered two children, a boy and a girl, with an orc woman. These had the lower body of a worm and the upper body of an Orc and multiplied among themselves, resulting in an even more hideous brood. The shamans of the Orcs call them Warat'Grom and consider them to be the cause of earthquakes and responsible for the disappearance of many of their tribesmen. But it is there that Cthupheen's pactors are found. It gives them the power to travel through the earth, even over long distances. And they can call the Warat'Grom to assist the Pactier in a battle. Ijothu and Shoggu Hai, however, are rarely summoned because they are considered very devious and even Cthupheen is said not to trust them.
