They farted around at Dingo Falls, realizing the ghost wanted justice/revenge for his murder, but left him to haunt the falls and headed into the desert.
They traveled four days into the outback, survived a sandstorm. They found an old mining site that was abandonded, but there were human skeletons, strange prints in the sand, and a collapsed mine shaft. One tent was still being used. A madman, Jeremy Grogran, guarded by magical dingos was still here. He told a frightening story of an American, John Carver, who set up the mining operation then killed all the men with horrible creatures from the sky.
They left the madman to his own devices and made towards the coordinates. They narrowly escaped an ambush by Koori tribesmen rolling boulders down onto their trucks and fled onwards, the Koori in pursuit on foot chasing the trucks.
They came to a camp. There were trucks, they recognized Mortimer Wycroft’s truck. A shed surrounded by sandbags had a single white guard that they killed. Stairs went down, a generator powering a line with bulbs to light the way.
The stairs descended 200 feet to an unbelievable ancient buried city of cyclopean scope. Bats roosted at the base of the stairs. The line of lights went into the city. They city buildings down here were huge and somewhat intact. The openings were all curvilinear and the buildings had stairs instead of ramps. It spread out in all directions a sense of awesome size and scale overhelming them.
Following the line of lights, they heard another generator and found a very large lit building. From the trash and supplies around they guessed it was a barracks of some sort, probably housing a large number of cultists. Father Mike ran back upstairs to get the dynamite he bought, but saw the Koori tribesmen from the ambush coming. He also noticed a strange high wind rise up and heard an eerie piping sound that seemed to greatly frighten the tribesmen. Father Mike fled back downstairs, abandoning the idea of dynamiting the building once he realized its size was too much for one stick. The line of lights beckoned on, but they fled into the darkness as they heard their pursuers on the stairs.
The darkness of the cyclopean city was overwhelming and they had a crazed mad dash into nowhere. Soon they noticed more light and came to a lit plaza ringed with electrical lights, a line of lights leading off in two directions. The plaza had a large pit from which came numerous screams and cries, including one clearly of a baby crying. They fled back into the darkness without investigating the pit.
Another crazed dash through endless blackness and after an indeterminate time they found more bulbs lit on a line. Following that to the left they came to another plaza, this one with a humongous purple fleshy mound pressing up through a hole in the floor, bound and bulging in a ring of stone holding it. They soon enough realized it was alive and merely the tip of some gargantuan creature bound by the ring, the unseen bulk of it beneath the floor! Madness!
