A goblin

"You're not from around here are you ?"

The goblin look at her calmly, yet with what appear tiredness.

"Are you a muggleborn ? if so i would like you to follow me to the bank, i hope you understand we cannot allow a muggleborn to wander without direction."

Harry hesitate a moment, she could go along with it and pass for a simple muggleborn witch until she found a way to reverse the transformation. In fact it could be fun to be someone else for a while. A shiver of excitation course through her at the idea of being able to do what she want without anyone telling her othertwise. Something that Harry was obviously never allow to.
