Guild Wars 2

I play humans mostly and every time I choose the missing sister one because its not completely ridiculous (circus) and not completely cliche.
I chose the Missing Parents this time around because the sister story got a bit old.
Now that I have finished the final quest before the choosing of the three orders I can feel the immensity of the cliche weighing down on me. I feel myself collapsing into a singularity… lol.
But now to my question. I don’t know if I want to go through the whole game with the ultimate cliche hanging over my personal story. Does the missing parents/sister/circus storyline end after the first quests up to level 20 or so? Or does the story continue because if it does I will stick out with the sister story just to see how the less cliche one ends.

So…you’ve made multiple characters doing the sister story, and don’t know that it ends after level 19?
Ok.
Also, how is the Unknown Parent story cliche?

I want to know if the story continues after level 19 or if that is it.
And the having no parents, or having your parents die is cliche because just about every fantasy game uses it.

Well, you’ll be glad to know that it doesn’t matter what you choose, your biography questions during character creation stop after the level 19 mission
