HIIIII!!! I'm Tracey!!! (: SO EXCITED that you're joining us!!!! I have like 294839483243 characters so bear with me while I word vom all over your intro post :3
This guy is Augustus Rookwood. He's an auror. He BY ALL INTENTS AND PURPOSES looks like a super chill guy: perhaps overly flirtatious, but genuinely charming and friendly, and seemingly very fond of muggle things. In reality, he's been training for 15 years to be a spy for Voldie. BUT his big ~inner conflict~ is that, now that he's been all pretending to love muggles and their stuff for so long, he's actually kind of...well...actually liking them. So he's going to struggle a lot with the dark/light sides of his personality. Etc Etc Etc.
Esme Taylor wordsfromheart is a super sweet/friendly/nice 6th year Gryffindor who has abandonment issues from her uber-religious parents disowning her after finding out she was a witch. She probably thinks he's kinda cute and I can see them being VERY good friends!!! (:
Gideon Prewett giddyupprewett is a 5th year Gryffindor who is super chivalrous, loves Quidditch, and likes to get into fights. He's pretty laid-back so if they know each other, they'd probably get along well.
Hana Jeung hanajay is a 7th year Hufflepuff. IDEK if they'd know each other, but Hana is bubbly and likes hats and pillow forts, and making chicken soup.
Natalie di Piero mlledipiero is the DADA Professor. How is he at DADA? I expect she'd like him because he's studious and respectful.
Emmy Wilkes emwilkes is a 6th year Slytherin...unfortunately I can't see them getting along very well. It would be weird e_e
