Shadow says he'd rather remain the unknown force behind star wars for obvious reasons. I had found this a couple months ago from a fan question
On May 16,2007 this is what someone wrote to him and his reply
"SS, how’s it going? (SuperShadow: Feel it coming. It‘s knocking at the door.) I was wondering if you could tell me the midichlorian counts of the following Sith/Jedi and their rank as most powerful of all time: Marka Ragnos, Tulak Hord, Ulic Qel-Droma and Nomi Sunrider. Please post and keep scoring. Thanks. (SuperShadow: Lucas says the characters you list do not really exist. Hence, no midichlorian number or rank.)
Then on May 19,2007 a fan wrote this in response:
Hei! You and Mr. Lucas have said in the comment from May 16th that Marka Ragnos and the other characters don't exist, but they are the heroes of the Dark Horse Star Wars comics and also you mentioned Marka Ragnos in your web site's History of the Jedi and Sith. You should decide yourselves. (SuperShadow: Lucas is uncertain of the existence of Ragnos since Lucas didn‘t create that character.)"
So in a matter of days Marka Ragnos went from not existing to "Lucas" being unsure if he existed yet Ragnos was in history of jedi and sith. Ragnos is also an EU created character. He was caught in a lie and made a bad excuse. But then again if he did make a legitimate mistake why not man (even if he is really transvestite) up and admit it?
