National Gobstone Association

The National Gobstone Association is an wizarding association dedicated to promoting the game of gobstones. It hosts the Gobstones World Championship, of which Kevin Hopwood is the current champions.

The association has tried earnestly to bring the game to greater popularity, but with little success. Its recruitment campaign, "Give Gobstones A Second Glance", features a poster with an accompanying picture of Hopwood being squirted with an eyeful of gunk, which may have done more to drive interested parties away than promote the game.
