The Northern Reaches
The Dwarven Clans
The dwarven clans are named after the ancestor spirit they are beholden to, often the one they believe to be the first dwarf. While the source of this tradition has been lost to time, it has caused so many wars that if there was a singular first dwarf, the probability is high that his name has been lost among the defeated clans.
While the dwarves do claim to have had an ancient, world-spanning empire that was better than all other ancient empires, there only evidence are wonderfully crafted halls and tunnels of stone beneath the earth. Yet, no dwarves actually LIVE in these spaces, and the script found on various landmarks therein is not dwarvish. Ergo, most non-dwarves don’t believe them.
