Drak - The name of a quaint, yet troubled village in my early DnD days. (This includes all the other variants, i.e MrDrak, Drakuss, TheDrak). It is unfortunately very common.
Korpulence - Name I used for Steam when Drak was taken, a small spin on the first random word that popped into my head.
Xaylam - Used this when I played Runescape with my buds, I wanted to be more original than most players, so I fooled around with some letters and got what's probably my most original alias yet.
Vector/Vektor - Names I used for a few games when Drak was taken, based off a real word that I thought sounded neat. These names never really stuck.
