Halfling
Halflings gravitate towards bucolic havens where family and community help shape their lives. That said, many halflings possess a brave and adventurous spirit that leads them on journeys of discovery, affording them the chance to explore a bigger world and make new friends along the way. Their size - similar to that of a human child - helps them pass through crowds unnoticed and slip through tight spaces.
Halfling communities come in all varieties. For every sequestered shire tucked away in an unspoiled part of the world, there’s a crime syndicate or a territorial mob of halflings.
Halflings who prefer to live underground are sometimes called strongheart halflings or stouts. Nomadic halflings, as well as those who live among humans and other tall folk, are sometimes called lightfoot halflings.
