Hogwarts Tales: The Mystery of the Dark Potioneer

"My dear Ellie..."
"Whoever the creator of this potion is, is after the same dark wizard that's been hunting my family for the past 10 years. This person... they know and they're after something. I believe this phial can lead me to the answer I need to protect my bloodline from being tainted further."
"I'll allow you to keep it as I trust you completely. Even though you can be quite reckless most of the times, I can at least be sure that you'd never put the safety of others in question. Talk to your brother about this."
"I will, professor. Thank you for your trust."
"Also, I needed to ask you for a very important task."
"Didn't I just did that? You wanted to know what was inside the phial and I gave you the answer."
"I also want you for something only you can do. I want you to find the creator of this phial."
Ellie's eyes widen in surprise at her special request, totally not expecting it.
