I'm surprised I havn't been able to track this down anywhere, so I'll start off here, one I'd like to see is Garb's...
My name actualy traces back to my Warhammer days, my favorite race, the Dark Elves, became my life to some extent. I knew all there was to know about their society (God I was sad!). My favorite class were the Black Guard, the guards of the king himself.
I created a unique character (who I drew, thats the man with the pointed sword seen in most of my signatures over time) who I named the Silver Guard. And that my friends is the origin of my username!
