I am watching Duck Tales on YouTube these days. I think the opening episodes of the series would make for an interesting series of adventures.
A mysterious old man breaks the Beagle Boys out of jail. In return, he wants them to break into Scrooge's money bin and steal a model ship.
The model ship is actually an ingenious map leading to a sunken ship filled with gold from the Valley of the Golden Sun. The twist is that the ship sank miles inland after sailing over flooded plains during a horrific monsoon season. Following the map proves difficult because it was made using the flooded landscape instead of the dry, desert landscape that normally exists.
The design of the coins in the treasure is familiar only to a few sages who study ancient history. They know the design is from the Valley of the Golden Sun and that the last known appearance of such coins was in a remote mountain village. Traveling to the village reveals that the descendant of one of crewman on the sunken ship lords over the locals thanks to his possession of the Golden Sun coins (revered as religious artifacts by the people there).
This "high priest of the golden sun" possesses his ancestor's half of the map leading to the Valley of the Golden Sun. In the show, he commands the people because he possesses the sole Golden Sun coin until Scrooge shows up with a single coin from the sunken ship. Since two "high priests" are now present, the people follow either one's commands. The high priest demands Scrooge's coin in return for his ancestor's half of the map.
The other half of the map was taken by another of the crewmen from the sunken ship. He decided to leave the remote mountain village and set sail on the open ocean. The currents lead him far south to a frozen tundra. There, he met an ice people who horde all the colored objects they find. His map was confiscated to be put on display in their museum and he was thrown into a prison cell and left to die. Scrooge and company showed up and managed to abscond with the second half of the map.
The map showed the location of the Valley of the Golden Sun. They arrived on a wide caldera ringed with humongous golden disks hanging on the inner lip. Far down below, an ancient, vine covered temple made of solid gold still stood undisturbed. Making their way inside, they were faced with three doors. Behind the first was an endless expanse of golden coins. Behind the second was a similarly endless expanse of gold dust. And behind the third was a solid wall of gold bricks. Opening all three doors, however, trigged a trap that would ultimately destroy the temple.
The volcano below the temple was filled not with magma but with liquid, molten gold. Upon triggering the trap, the golden disks lining the caldera's lip hinged out and reflected the sunlight into the temple and down into the molten gold. The magnified energy of the sunlight caused the liquid gold to boil over as the temple began to crumble. Finally, the caldera fell in on itself, burying the temple and everything else beneath hundreds of feet of rock and earth.
Working from that general outline could be a way to engage players in the Temple of Venkatesh.
