The story of the golden tower is oft repeated in the scripts of the ancient civilization, and the libraries that have been discovered hidden below the world's surface. The paper, well preserved because of the contained environments, allow for the researchers of the museum to translate and suss out clues as to the location of this tower.
So far, the search has been fruitless.
However, there's a good lead found in the archives suggesting that either the tower or another object of great value is in a jungle temple, set in dense foliage on an island.
Inside the temple is perilous. When invaders enter the bottom floor, they run the risk of tripping more cave-spider poisoned darts, as with the desert temple. The foliage and overgrowth also makes for excellent camouflage when one is a creeper searching for someone to blow up beside of. Especially as the second floor is near dark.
On the upper floor there's another row of darts holes, but also a series of three levers. One set position of the levers will deactivate the darts and allow someone to pass them (↓ ↓ ↑) and another position will allow a panel to open (↑ ↓ ↑). Inside the panel is a chest, and in this chest is the motherload.
Several gold bars, some large cut diamonds, some actual emeralds (the money once used, not the credits named for it), and the most important of all, the diamond sword.
The golden tower is, unfortunately, not here. But this particular item can bring a lot of money, as can the gold and gems. Either returned to the museum for a reward, or sold to the Orions for even more. The problem is it will take at least two people, since after the darts are deactivated, someone has to flip the switches to open the panel (which reactivates the dart defenses until they're turned off again).
