Morgo the Mighty takes place in Surrilana, a vast cavern – series of caverns actually – beneath the Himalayas. Our protagonist, Jerry McRory, is hired to fly a plane through the mouth of a cave in the side of one of the mountains. While McRory believes that his employers claims of a great treasure are nonsense he never stops to ask what seems like a more obvious question – “Where I going to land this plane in a cave?”
