The Jalsavrah Pyramid, also known as the Tomb of Kings, is the burial site of the pharaohs of Sophanem and Menaphos and the location of the Pyramid Plunder minigame. It contains many well-guarded riches and therefore being eyed by Tarik, an associate of Simon Templeton's.
There are four entrances around the pyramid, each decorated. Three are empty, and one has the guardian mummy inside of it. After speaking to him, the Pyramid Plunder minigame will begin. The door which leads to the mummy changes every now and then.
Inside, there are eight chambers, which the mummy allows the player in - each dependent on the player's Thieving level. In each chamber, there is one sarcophagus, which may be looted for a chance to obtain the elusive Pharaoh's sceptre.
The fastest way to get to the pyramid, and Sophanem in general, is the teleport function of the Pharaoh's sceptre. The next fastest way is teleporting to Pollnivneach via a redirected teleport tablet and taking the magic carpet to Sophanem. Taking the carpet may cost coins depending on the player's completed tiers of the Desert diary, progress in the clothing section of the Rogue Trader miniquest, and usage of the ring of charos (a). You can also teleport to Nardah with the Desert Amulet and then run south-west to Sophanem.
