Do we still have Dark Arts adjacent group of peoples at Hogwarts? Or did they all graduate?

I am in need and figured I'd ask before I put something in the Lonely Plots section.

I basically want to send Morgan down a bad influence path because she's become terribly lonely and desperate for attention in my head, especially after her sister drama and her struggles with her own magic, and that has a tendency to appeal to a certain crowd. I want to use her angsty nature and start her down a Slytherins path of ambition and darkness ~ When I originally apped her it was originally my thought/plan for her to become involved with Amaranth's [url=https://charmingrp.com/showthread.php?tid=13218] Nightshade Society [ /url] but since Cherry's no longer here and Amaranth would've graduated I'm wondering what else, or who else, is available that could work and draw Morgan into the darker elements of magic etc or at least into the mental or wandless arts......
