An eventure is akin to a normal adventure, but does not (normally) feature violence or physical challenges. Instead, an eventure focuses on the use of social skills and role-play to resolve the challenges, or events, therein. Most eventures take places in a settlement or on the road. Few occur in traditional adventure locales such as dungeons, ruined castles and so on.
Eventures are an excellent change of pace and can be used as filler between adventures or as situations in which PCs who have invested in social skills can shine. They are also perfect for players who enjoy role-playing.
