History
Once, Addison Delamar send a transmission from there, disguised as Jack Harkness to lure the Doctor to Gharusa Prime, so she could buy Jack's body scan info from the Slitheen foundry on Gharusa Prime in the first place. (COMIC: The Bidding War) This was part of her plan to capture the Doctor to sell his memories to the highest bidder after he put his brain up for auction. (COMIC: The Bidding War, Weapons of Past Destruction)

While travelling with the Ninth Doctor and Rose Tyler, Jack saw the transmission on the TARDIS's scanner, but wasn't able to remember sending it.

The Doctor recognised Gharusa Prime because of a skyscraper in the background of the video, the Delamar Solar-Needle. Therefore, they went to Gharusa Prime to investigate the origins of the message and discover why Jack couldn't remember sending it.

Upon arrival, the trio were immediately confronted by Doctor Who?, a show based on the Ninth Doctor and acted by Slist Fayflut Marteveerthon Slitheen. While the genuine Doctor was arrested for identity theft, Slist was mistaken for the Doctor by the Raxas Alliance and brought to Clix, taking an unconscious Rose with her. When the Doctor had convinced Investigator Estiva to aid him, the two and Jack Harkness found the Slitheen foundry and interrogated Penny who pointed the Doctor and Jack towards Clix.
