Fauns are not as common as some stories might indicate. They rarely show themselves in even the most sheltered of circumstances, tending to keep to themselves much like introverted halflings. They like to find protected lands where they can be left alone by everyone but their closest relatives. And even some of those aren't welcome sometimes, as fauns are very good with setting boundaries. They do have a soft spot for the vulnerable, and almost intuitively will show up to help at the most opportune times.
Fauns first appear in the circles of the Blackburns when one of the more common places they congregated through the years was overrun by an icy witch whose wicked influence plunged their world into a never-ending winter.
