I see people are still posting summerfest entries and going back to prompts from the first days, so I'll indulge in it too. Mages Guild's Fair! I'm sure it was quite common, at least in the first years of the guild, to promote the organization through community events. The goal was to attract people who might have benefitted from the guild's services, or to discover new talents among the less fortunate. The fairs usually involved visual demonstrations of all the schools of magic (which hadn't, technically, been categorized yet!), followed by interactive activities that promoted the normalization of magic in the day-to-day life. On the side, business was talked about between guild members and possible employers.
