The Scarab Wall[29, 90] lies at the southern edge of Silithus, marking the boundary between the silithid-controlled desert and the ancient kingdom of Ahn'Qiraj (controlled by the more intelligent qiraji). It is an impressive structure, including some sort of magical shield that also prevents creatures capable of flight to simply fly over it. The foremost feature of the wall are the Gates of Ahn'Qiraj.
While in-game a player attains the rank of Scarab Lord when opening the wall, it is known that Shiromar was the one who rang the gong in lore. This potentially means that she is the Scarab Lord when it comes to the storyline.
