Alexander's Temple (Location)
A treasure location in the Isolated Desert. You'll explore this one during the Plight of the Rebels side quest.
There are two treasures here, on inaccessible for the moment, the other in the eastern ruins, by a king snake.
Take out the many snakes here to claim the treasure pouch.
The second treasure is available only via a secret passage in the swimming hole to the south of the main temple.
Swim through passage, and follow the tunnel through a crack into a roomful of snakes.
Kill them.
When they're all dead (and remember that even snakes grant a headshot bonus), loot the white chest to the left to complete the location.
