Please meet Ida Chang! Very academic type and liable to humblebrag about her 5 Os on NEWTs. Kind of like the curious cat who may or may not die one day from her experiments, most recent accomplishment being to turn a criminal man into a dog. Her probability to scheme/be friends is high if they get discuss any research projects. Reasons to meet- her family (unplayed) owns Chang Imports of the Orient, a flourishing herbs/ingredients biz that stocks up a number of exotic ingredients in of potions closets in Hogsmeade & Hogwarts, & she occasionally helps with the business. Or at society parties I'm sure (her friends are scheming with ways for Ida to 'marry up' so she's going to be at a few events).

Thomas Harvey can work any soiree that needs an accomplished mixologist, or, he and his friend head up a private investigations business should Henry ever have the need for ~discreetly finding out something.

Finally have @"Sophia Voss" and Cassian Valenduris for random encounters that can range from theatrical performances to the casual run-in with the law.
