Aftgard
From AmtWiki
Aftgard, or After-Amtgard, is where Amtgardians hang out outside of an Amtgard activity. This can involve tabletop gaming, going to the movies, dining in a restaurant, or some other mundane social activity.
Aftgard is regarded as an important aspect of the Amtgard experience for a number of players, as this can provide a more casual setting in which players can foster friendships, connections, etc.
