Gnome

Gnomes are one of the humanoid races. Gnomes were the oldest sentient race on the Continent and together with dwarves and elves are called the Old races. Gnomes are shorter and weaker than dwarves, but just as tough and more agile. They can be easily distinguished from dwarves and halflings by their long noses.

Many gnomes live in Mahakam along with the dwarves, although others inhabit the Tir Tochair mountain range. They are excellent smiths and metallurgists and their gwyhyr swords are considered the best in the world.

There are no gnomes in the game, although some of the characters do muse about Kalkstein's origins. Kalkstein is certainly never specifically identified as a gnome. It is said that he has a passion for gnomish alchemy.
