I saw some a post where somebody was making assassin names, and this stuck out and well... I've been using a variation of it for a while. [Aesthetic, Aesthetical, Dark, Silent, Evil]
Before that I was using Dark Crusader because I've always been fascinated with the medieval ages and whenever I use Dark Knight, it is always confused with Batman.
Before I came around to the point that everyone was misinterpreting what I meant by Dark Knight, I used Dark Knight or a variation. [Fire Knight King was one that I used, Fire because I've also always had a fascination with fire, the beauty of the flames, knight for the afore mentioned reasons and King because of Metallica's King Nothing. That and it conjured a pretty awesome looking character in my head^^]
Before that though it was Charamaniac. [Because of my love of fire, and the poke'mon Charizard, who I maintain is the coolest poke'mon of all time.]
And that covers my history through screen names, you've been a lovely audience thank you very much^^
lol.
