Go and have a long think about the name you want to choose, even have a look at which race you want to be first and do some research about your chosen race; you don't want to be a Wookiee named "Mike Smith" now, do you?
This name will follow your character and the actions you do in-game, until that character dies. So, keep that in mind: You never know, you might be around for the next eleven years...
Also, whenever you are trying to make a name, always ask yourself if you would want to introduce yourself in public with that name. Obviously female names when you are male etc would need you to imagine a bit more, but you wouldn't walk up to someone in the street and say "Hi, my name is Fury X6X. Nice to meet you."
I did a quick search of it, and it came up as various Welsh legend names and such like. Especcially Cadwgawn. Cadfael may be allowable. We try to keep famous and well know names from other universes etc to a miniumum as much as is possible.
If you replace the first name with something different, it will likely be accepted, so long as its not famous etc, as per the rules.
Blimey so Cadwgawn Cadfael is a valid name but cause it has a link to a Welsh legend that no-one unless your Welsh has ever heard its not acceptable? Its a rare name but is still around today and names like luke, john, matthew are names of biblical proportions so does that not rule them out too under your rules? I really wanna sign up and I like the idea of having a valid Welsh name because its unusual
