Gnome

Gnomes are shorter than humans, about 70% of height and 45% of weight. Note that weight doesn't scale linearly with height, and that if all proportions remained the same as humans, they would weigh significantly less. In fact, Gnomes tend to have very high body fat percentage compared to other races, an adaptation that helps them survive in the cold. They have wider, stockier builds They are built to have very efficient internal temperature maintenance. Their skin ton is very light, and their hair and eyes can be any color.

Females are little bit smaller and more compact, but there is not significant difference in muscle mass and ability to build muscle.
