Guild Wars 2

Is there any way to reset my personal storyline to the very beginning? I have spent hundreds of hours on my main character completing everything I can. I spent a fortune and time getting my cultural armor set, and the Commander ability without playing the personal storyline yet. And when I do, I made several wrong choices along the way, and I ended up with a permanent condition that cannot be changed in any way I know.

For example, when Logan asks about my dead sister and her lineage, I didn’t know it was suppose to affect her appearance. Now with my character having bright skin and blonde hair, I’m stuck with a tan skinned dark hair sister that looks nothing like my character.

I don’t mind having to reset the whole thing, the whole instance and redoing the whole storyline all over again. Isn’t it just a matter of resetting all the data flags of my character to 0, back to the point I just got out from the battle of Shaemoor?

I don’t want to have to delete my character and leveling everything from scratch. It’s only my personal storyline.

Is there any way?
Even on the GM side?
