Guild Wars 2

I have a friend who tried out the game by creating a character on my account and playing when he was visiting me.
Now he wants to buy the game himself, but he would really like the character he played transfered to his new accoount.
Is that possible?

Nope, characters are bound to account. Also a bit nit-picky but technically you are not supposed to share your account even if you are sitting there with the person. The two combined is why transferring that character won’t be a possibility.
