Ig the worldbuilding for my custom 5e setting counts? It’s sort of a continuation of the forgotten realms, with a heavy dose of Warhammer 40K and Doom thrown in. The world of Toril was shattered, and the fragments frozen in place by a divine sacrifice, leaving each landmass cluster within reach of one another (within Voidships).
The government in question was the Dwarf Assembly. It’s a loose confederation of citadels within these clusters. Each one dedicated itself to one trade (for example, mining clusters, smithing clusters, etc.), with each trade being led by the oldest dwarf. Assembly-wide decisions are made with the agreement of all clusters.
Tensions rise within each cluster whenever a problem cannot be solved by tradition, with older dwarves being quite proud and reticent to veer away from it. Tensions rise within the Assembly whenever a younger elder is introduced, being seen as inexperienced.
It’s not meant to be perfect, I wanted it to be a source of dramatic tension whenever the party ever stepped foot on dwarven soil. I also really like the mental image of dwarves with ushankas.
