Describe Hylar Dwarves here.
And here again.
The dwarves of the mountain kingdoms existed apart from much of Ansalon throughout their history. Since their contact with the outside world often turns out badly, the self-sufficient dwarves are quick to shut their gates and seal off their halls to preserve the way of life that has sustained them since the Age of Dreams.
Hylar (highest): This is the oldest of the dwarf clans, often considered the most noble. Their halls within the mountain kingdoms are the best appointed and always magnificent.
