D&D 3.0: Tales from Mystara
Classes: Dwarves prefer the Fighter and Cleric classes and dislike the Druid, Sorcerer and Wizard classes (dwarves of these classes do exist but are few), but otherwise they have no restriction on the classes they can choose.
Mystara Locations: The main dwarven nation is the Kingdom of Rockhome but there are mayor dwarven colonies in Kingdom of Karameikos, Alphatian Empire, Thyatian Empire, Northern Reaches and the Republic of Darokin. The dwarves cannot live on the Principalities of Glantri or the Broken Lands were they are hunted. There are almost no dwarves in the Kingdom of Alfheim.
Social Class: Dwarves from outside the Kingdom of Rockhome cannot be from a Social Class higher than Wealthy/Untitled, any roll result higher must be lower to that social class level.
