When originally making my character Cain Azrael, I tried every variation of using Kain as a forename. The surname was my intended original. Anyway, I eventually gave up thinking that every combination that would result in me coming up with a name that didn't make sense was taken. I've looked up every Kain name I could find on the main website however & to my surprise the name without some sort of silly additional text (Kainn, Kain', Kain'd) doesn't exist. I can get not wanting people to copy your flagship characters, but then I noticed the hundreds of Strife, Highwind, Zell Dincht, & so forth named characters. I don't understand why this one name is the exception.
