I have Mason Skeeter Puff HoH and herbology professor! He's been there for ten years now, starting in the 83-84 school year, last year was his first year as HoH. He's usually pretty unflappable and available around the school. But you'll often find him in the greenhouses more than his inside office. I will have another Hogwarts contact after the AC too

I also have Ramona Pendergast coming in as a first year, she'll enjoy Astronomy immensely!

outside of Hogwarts I have Ziya Burroughs who was a year behind her in Ravenclaw, but generally pretty outgoing and social at the time! Sydney Podmore was also a year behind in Slytherin, same deal, though he was a bit of a dunderhead back in school lol.
