Super short version? The commons was adorned with balloons and streamers and there was cake and snacks out, most of which was more-or-less homemade!
Fake Edit: I don't know exactly if I want this to be an actual RPed out thing or just a background event. That's the kind of thing that'd be rather too cumbersome to actually play out, so I'm inclined to just have it be something that was noted down with people's reactions to it or something. Hooray!
