Follow up. Harry Potter has quiddich. Are there any magical sports in the realms/sanctioned in waterdeep?

Lots of sports, covered in web articles and website replies down the years. Card and dice games in Volo's Guides, El's Realms, and elsewhere. Oh, yes, sports are covered, but were downplayed in TSR's published Realms due to company fear of lawsuits if fans hurt themselves.
