Gnomes

Throughout all the Known World, the scattered warrens of the gnomes are bastions of good nature. A strong sense of community, duty and empathy makes gnomish neighbourhoods some of the most lovely places around. A traveller down on his luck who stumbles into the small community of gnomes is all but guarenteed to receive the best care of which he could dream to ensure he is well rested from his journey so far and well equipped for the remainder. This benevolence is sometimes misplaced, however, and the sweet gnomes become exploited by black-hearted nerdowells.
Forest Gnomes:
Making their homes in the gentle woodlands across the world of men, the forest gnomes pride themselves on a saftey derived from a oneness with nature. A sure sign of a nearby forest gnome village is that the forest around one seems to brighten, becoming friendly and agreeable. Many a child has wandered into the forest, against the commandment of its parents, and avoid a grizzly end by falling among the forest gnomes who will dance and play with it for a spell before happily guiding it back home.
Their natural kindness has garnered excellent relations with the surrounding nations of men, dwarves and halflings who respect the gnomes want for privacy and so they live in peaceful coexistence.
An rather exceptional time in the history of the forest gnomes follows the Winter of Death the world was blanketted by four years of permafrost. The men of Krussna accused local gnomes of hoarding supplies and playing favourites with whom they shared. These allegations were unsubstanciated but enough to spur men whose family starved in the Winter to drive out the gnomes and the villages they supposedly favoured. This group of refugees fled into the mountains where they found an abandoned dwarvish city, founding the Principality of Gyanlund together.
Rock Gnomes:
Rock gnomes have carved out an existence into the mountain ranges where they are safe from most natural predators. The thick stone walls of their hives keep out the chilling wind and keep in the thrum of a bustling neighbourhood. It is in these high homes that rock gnomes delicately craft all sorts of gizmos and gadgets which ultimately serve no purpose save for giving its creators the greatest understanding of technology in the world.
Food is scarse in the mountains and thus most rock gnomes subsist on a diet bereft of animals. They relly on subterranean farms to cultivate various breeds of fungus and see surface plants as a delicacy to be enjoyed on occasion. Their creative spark is extended to their cooking and while the ingredients may not be particularly interesting rock gnomes go to great lengths to turn them into gorgeous meals.
Deep Gnomes:
Far beneath the surface world is where one will find the hardiest of gnomes. In small caverns, as out of the way of the other races as possible, the deep gnomes create their modest homes. These homes are not open like those of other gnomes but camoflaged and fortified so that the terrors of the underdark do not rip them asunder.
The legendary hospitality of the gnomes is unfortunately lost those in the deep, hammered out of them by the trecherous landscape that surrounds. Deep gnomes must always be cautious of outsiders lest they wind up slaves in the neverending industry of dark elves and obsidian dwarves.
Rules:
Playing a gnome or gnomette in the Known World necessitates the corresponding rules in the Dungeons and Dragons Fifth Edition Players Handbook, though additional rules needed to play the deep gnome are found in Mordenkainen's Tome of Foes. The language rule is modified in all gnomes such that you can speak, read and write Gnomish and one other language of your choice.
