I'll give a bit of history and other facts...
The Dwarves claim descent from Seven Fathers who lived in the First Age and as a result, are divided into seven Folk, each with its own King and ancestral halls. (When Sauron forged the Rings of Power, he made one ring for each of those seven Kings.) Dwarves are short, about 4 1/2 to 5 feet tall, but strong and hardy. Their average life-span is about 250 years and if they married it was generally at the age of 100. The Dwarves are great miners and craftsmen of stone, metal, and jewels. They have their own language, 'Khuzdul', but it was secret and never spoken in public. The names by which they are known: 'Khazad' by themselves, 'Naugrim' by the Elves in the First Age, and 'Nogothrim' in the Third Age.
