The Ogremoch Mesa is an unnatural plateau surrounded by mounds of earth and spires of rock. Inside the plateau is an open rift to the world of Granitoid. Named the Togomud Sink, this rift continuously spills alien matter outwards. Like the causeways of a dam, these rivers of otherworldly mud, sand and rock are directed outwards. The largest of these rivers is the Mud Flow.
Ogremoch Mesa grows in mass and height with each passing decade. Since the opening of Togomud Sink in 1687, the plateau has reached a height of 3,400 feet.
Tachylyte, capital of Rilirthad, is sited atop this plateau. The walls of this city are built like a series of steps, each a great canal redirecting the churning mud and rock away from the city.
