Halflings are native to most of the Eastern Continent, but a lot of them live in the southern jungle.
One bigger clan resides by the lake of Pel-Holina, where they worship the Deenja ruins.
This clan has a history of being slaves to the grunt, but after several generations of being free, having risen up with the help of the Triton, they have a mostly equal place in society there.
The rest of the Eastern Continent sees quite a few halflings all over, and they have also migrated to especially Belanna as well.
