Hello Christian and Fern, welcome to both of you!
Christian - Someone please correct me if I'm wrong, but you could probably create and weave any legends, tales or stories that you want provided they aren't a set-in-stone plot that contradicts something students ought to reasonably know or that is canon? I think RE: The Hallows, it's up to your interpretation, the kind of information your character is coming into contact with and the accounts.
Fern - Are you possibly talking about the avatar? (When you hit 'photo' under 'edit my profile.')
If so, avatars (which you can see many sorted students have on the left side like mine <) are not currently enabled for Pre-Hogwarts Students. You can see that you currently have a grey avatar, and upon sorting you will be able to upload a photo that is under 50KB and no larger than 130 x 300 pixels.
I also believe that the import option where you can enter a link to be your picture doesn't work (someone correct me if I'm wrong!) and that when the time comes when you can have an avatar, you can save it to your computer and upload it by hitting "Choose File."
I hope this helps! <3
