You don't have to register with your real name, just any name that isn't that of your character's. Also, it's kind of obvious you didn't pay attention to anything around here, because if you had you would have seen that Norway was already taken.
The system can not give you an avatar, you would need to put one up yourself. This place doesn't have any avatars to give you. It doesn't "just happen", it doesn't work like that.
And no, we have no suggestions. You need to choose your own character, one that isn't already taken by someone else.
