End of the Last War
There is no great dwarven empire of the past which they are trying to reclaim, unlike many settings. The dwarves were barbarians who settled in the Mror Holds millenia ago, but were not civilized until the coming of the Galifar empire. Since then, many dwarves have spread across the continent, integrating themselves into whatever society they find themselves in. However, just as many dwarves present in greater Khorvaire these days are emissaries of the Mror Holds, with dwarven smiths creating some of the finest mundane items today, while the dwarves of House Kundarak run the banking system of the continent.
