Shaa-Dom was a Dark Eldar city of the Webway and satellite realm to Commorragh. The seat of power of El'uriaq, Shaa-Dom and its overlord planned to one day dominate the Dark City. However the supreme overlord of Commorragh, Asdrubael Vect, captured a human starship and sent it crashing into Shaa-Dom through a Webway Portal. The city was devastated by the initial explosion, but the real damage came when the ship's Warp Drives detonated and opened up a rift to the Warp. Now flooded with Daemons, Shaa-Dom was sealed away from the rest of Commorragh on Vect's personal orders.
