Halflings are a peaceful race, known by many races as the small folk. They live in close-knit agricultural communities and are generally a home-loving people. When out in the world, halflings generally avoid notice entirely or ingratiate themselves with everyone around them. Halflings can be fairly diverse in appearance, some being categorised into distinct sub-races:

Distribution
In The Known World, halflings originate from central Tide, in the area now known as Middenfall. Halflings have had an impact on human culture, teaching old farming techniques to the later human settlers. Halflings outside of Tide are rare as very few like to travel beyond their homestead, outside of their homeland they're often mistaken for small humans.
The only large group of halflings outside of Tide are clans of ghostwise halflings on Korona Morska.

Halflings are almost nonexistent in Arauglbrok, as they originate from the opposite side of The Great Rift.
