From publisher blurb:
One of the most iconic creatures found in most high fantasy games, halflings have been part of the game since the beginning. In Sundara, though, they’re more than just hillfolk with a love of quiet life. From the hard-riding shepherds of the Vale to the green-skinned forest recluses of the Suff Folk, and from the cloud-skimming Skycatchers to the seabound Tidelings, halflings in Sundara are anything but typical.
This book contains 5 separate cultures of halflings, complete with the sorts of social groups and environments they tend to fall into, along with notes on languages, a possible origin of the species (as distant cousins to dwarves, for those who believe in myths), as well as providing mechanics to customize your halflings to give this variety a bit of teeth.
As with all previous releases in this setting, Halflings of Sundara is broad enough that you can use it in any of your home games, while also slotting neatly into the growing Sundara: Dawn of a New Age setting for those who want to explore what else this world has to offer!
