Never heard of Sword of Stars. I've used Morikahn for about.. 16 years now.
My real name is Forest.
When I took Japanese at a community college class, the teacher had a hell of a time pronouncing my name: 'Fo-re-su-to' - san. To make her life easier, I found the Kanji for trees..http://18.104.22.168/wp-content/uploads/2008/09/kanji-forest-mori.png
And went by Mori-san. She liked that I guess. Then, as loathe as I am to admit it.., while playing a game of Command and Conquer, I decided to try to sound all cool, and added Khan to the end of my name, like Genghis Khan. Unfortunately, I misspelled it as 'kahn'. I didn't realize I had misspelled it for years... and by then, it was too late.
So that is the long and silly explanation behind my name.
