Rock Gnome

Rock Gnomes have a natural inventiveness and hardiness beyond that of other gnomes. Most gnomes in the worlds of D&D are rock gnomes.
A constant hum of busy activity pervades the warrens and neighborhoods where gnomes form their close-knit communities. Louder sounds punctuate the hum: a crunch of grinding gears here, a minor explosion there, a yelp of surprise or triumph, and especially bursts of laughter. Gnomes take delight in life, enjoying every moment of invention, exploration, investigation, creation, and play.
