When the dwarves first made contact with humans, there was a schism among the clans. There were those that wanted to interact with the newcomers, and those that wanted to destroy them. The latter group left their home mountains and settled in a small valley to the south. Those that stayed and dealt with the new race initially benefited from the influx of ideas, trade and gold, but soon stagnated as the rapidly changing ideas of the short-lived humans began to conflict with the long-term viewpoint and cultural respect for the earth held by the dwarves. When the elvish merchants made the scene, the dwarves were excited to have found another long-lived race, with whom they could share their philosophies and culture; unfortunately, the elves sought only a new base of customers. Despite their long lives, so thought the dwarves, the tall, pointy eared humans had the same shortsighted mindset of the humans. While the dwarves did do business with the elves, their initial attempts at friendship fell through quickly.
Resolute and stubborn, the dwarves of Budynsky have maintained their culture over millennia. While at the start of dwarven civilization, they produced brilliant works of art and technological innovation, in the recent centuries, they have begun to slow, much of their work has been devoted to maintaining what already existed, not creating new things. The slow-moving culture, so obsessed with what was, has led many young dwarves to leave their home and explore the world, which has led to even more stagnation, as most of the people who remain in Budynsky are the elders who are so conservative as to drive the young ones away.
Even so, the young dwarves that leave carry with them an inherit respect for what is old, and an urge to maintain the status quo, even if some fight to suppress that mindset.
