So, is it a single passage with doubled (+shifted) guards, or are there 2 separate entrances to the sand treasury?
The object generator places the generator near the cliffs on one side, and the guards on the other, so that it cannot be taken without a fight (not counting the bugged, shifted guards of the objects, where it is possible to take something without a fight). If we exclude the ZD (Zone of Death), I doubt that the generator intended to guard these two objects (Pandora and the Cloak) in this way; most likely, the reason for the lack of cliffs was the shifted Golden Dragons (this is a proven fact in the picture from VKL, where the gnomes created a passage to the treasury from their native spawn point - which is not possible on this template).
With 99.9% certainty, I assume that the Cavaliers and ZD guard the passage along the road (one passage), and the passage that appears behind the ZD is a bug.
