The good news is your application has been accepted in principle! However there are a couple of questions before it can be fully processed!

Motivation

You've told us what her motivation on the train will be, but what is her motivation before her life gets disrupted by void train adventures? You mentioned a heartbreak that made her start to believe her mothers teachings were wrong and that she used to be motivated by wanted people to like her but isn't any more. Does she have an aim in canon? Is there something she is trying to achieve?

Skills

As someone with fighting ability and also magic/potion making etc what is her 'default' if anything? When confronted with a problem is she likely to go straight for the sword or try and figure a way around things using magic and smarts?

Thank you
