I got the name "Ikarus" from Tanzwut - Ikarus and the "Hagen" from ... well, Hagen. Just mixed the stuff up and finish After that I used the name for various stuff, like WOT or my own phantasy badass universe ruler. This was the first name I heard in my head when i was registering to the forum.
My original name when i joined was Dot.Pixis. Name taken form attack on titan but my skype name is K.Reddy. Changed it so there would be less confusion
Hanzel Cloudstone was a terrible Marty-Stu character from the initial period of my RP (typing intensifies since 2012). Name's from Hanzel und Gretyl band's influence, surname's just steampunkish mishmash.
It stuck somehow, I don't know. I'm HanCloudstone almost everywhere.
