The Desert of Doom (formerly called the Serpentine Valley) was once a glorious valley ruled by the Pyro Vipers during the First Age that became a desert region in Ninjago thousands of years later. There is an pyramid in this location that the Pyro Vipers sarcophagus was in after their tribe died off. The ninja and Clutch Powers went to the pyramid but accidentally released Aspheera. This region has giant scarab beetles, and one particular giant beetle, Beohernie, was worshipped by local tribes in the region.
According to a legend, local tribes in the region worshipped a one-thousand-year-old giant beetle, Beohernie. Disappointed with its followers, it destroyed the village.
Thousands years ago, the desert was a valley inhabited by ancient Serpentine, of which Mambo V ruled. Humans were forbidden to enter the valley and Serpentine were not allowed to enter the land of men.
One day, a young Wu told Garmadon he wanted to go to Serpentine Valley. Garmadon reluctantly agreed, and they got caught and thrown in a cell. Aspheera then freed them in exchange for friendship and Spinjitzu lessons, with only Wu keeping his end of the promise.
Over the course of many weeks, Wu would sneak off to teach her Spinjitzu. She succeeded and used her newfound powers to overthrow Mambo V. The brothers saved the valley by using the Scrolls of Forbidden Spinjitzu and had her thrown in a cell that cannot be opened with magic.
Clutch Powers excavated the pyramid out of the sands and refused to explore it.
The ninja traveled to this location to help Clutch Powers enter the pyramid. Once situated at an oasis, they are attacked by Beohernie. While making their escape on the Land Bounty, the beetle eats off a crucial component for the Bounty to work.
Defeated, the ninja take refuge atop a plateau, surrounded by two more giant beetles.
After a night spent in the desert, the ninja come to the conclusion that someone has to enter the belly of the beast itself in order for them to escape. Zane enters Beohernie's stomach and was pulled out by the ninja allowing him to escape with the part.
After meeting with Clutch Powers and convincing him to enter the pyramid, he and the ninja explore it with the help of Professor Powers' book, Booby Traps and How to Survive Them.
When the group enters the main chamber, they find an ancient locking mechanism (that Jay compares to a puzzle,) and ancients words on the wall. While Jay attempts to solve the puzzle, Zane reads the ancient text. It reads: “Beware, ye who enters the Serpent's tomb. For her anger nearly did consume all Ninjago until a foolish boy. With a staff of power, Her evil did destroy."
Realizing their mistake, Zane tries to warn Jay to stop, but it is too late, and the tomb is opened.
From the tomb, Aspheera, a serpentine sorceress awakens. She asks for the boy who locked her up, but the ninja don't know who she is referring to. After a quarrel, she notices Kai's elemental power and steals it from him to regain her true powers. After locking up the ninja in the crypt, she chases Clutch Powers out of the Pyramid.
She commands her army of Elemental Cobras to attack Ninjago City, as the pyramid erupts lava, and Professor Powers is sent flying into the city on a piece of rubble that blew off from the pyramid.
The ninja make their way out of the ancient pyramid as it collapses upon itself. As lava flows through the ancient crypt, the Pyro Vipers are awakened.
Zane gets a flashback about the Desert of Doom.
