What: Academic Salon
Who: Hosted by Emilia Wright, invited at magical academic types. Mostly UC and MC, but 1-3 WC people who have made a name for themselves in these circles would get an invitation.
The way I see it, the invitations would be as follows:
If you're UC and upper middle class: because you'd run in the same circles as Emilia, if she merely knows you have ~academic interests, you'd be invited.
If you're lower MC and WC: because Emilia likely wouldn't personally know you, she'd only invite you if you are a known academic, have published papers, or a UC/upper MC person invited you as a +1.
Cost: Not really, but those in attendance can donate to a Hogwarts scholarship fund that Emilia is keeping.
Where: The Wright family estate, somewhere in England
Why: So the brightest minds can gather and talk science.
When: August 20th
