Rock Dwarven Cultural Traits
In addition to the more common dwarf communities who live beneath the hills, some dwarven communities develop above ground, high in the mountains or deep within ravines. These rock dwarven communities develop their own distinctive culture and practices, emphasizing defense of their communities as an important value.
