The Land of Corra
Whisper Gnomes are a cautious bunch, much more quiet and contemplative than their standard Gnome cousins. The race has no actual homeland, but is prevalent in the city-states along the southern shore of Muogamarrah. Unlike the common gnome, which tend to live underground in areas of rolling hills, whisper gnomes are very much at home in the city.
The largest concentration of whisper gnome clans tend to be in port cities, such as Tapur, but landlocked Muogamarran cities have seen their share of clans as well. Whisper Gnomes tend to blend in with the framework of the city where their clan lives, usually steering clear of city politics that do not concern their individual clan.
They are very naturally stealthy, hence their moniker, and make excellent sneaks and rogues. Combine that with the savvy, street cunning that seems to be honed by most whisper gnomes, and you will have several reasons not to underestimate one.
