Through the prismatic umbrage fly the archways and buttresses of the monuments above the catacombs of the Eaters of earth.
The Tomb of the Eaters is a the game's largest dungeon-like area. It plays a central role in the main quest.
The tomb is massive. It fills an entire parasang (3x3 zones) and extends for multiple levels upward and downward throughout that entire area. The tomb's exterior perimeter, which encircles that entire parasang, is constructed entirely of 
carved stone from the sultanate of each of the five sultans that preceded Resheph. This carved wall perimeter is dotted with many recesses that are filled with golden 
statues of Eaters that are in various states of dilapidation and decay.
Entrance
The entrance to the tomb is found in the Omonporch area, in a zone called Arcade to the Twin Gates, Omonporch, surface. There will be an elaborate brick walkway that leads to tomb from several zones to the south. The Arcade to the Twin Gates, Omonporch, surface is also the area where one finds 
Asphodel, Earl of Omonporch, a key character in the main quest sequence before the player enters the Tomb of the Eaters.
This entry zone includes the twin gates that seal the tomb, the 
Death Gate and the 
Life Gate. The player must eventually enter through the Death Gate in order to proceed in the Tomb of the Eaters questline. The Life Gate is not relevant to the quest and cannot be opened through normal means.
