You know the tale of Belesaria and the dan of the Brightblade dwarves. At least 100 years ago, the Brightblade goldsmiths lived in delvings in Daggerdale, In peace with the ruler of House Morn, the Mage-lord. The Mage-lord's wife, Belesaria, was a proud and arrogant woman, who believed that the people of the dale were her servants, not she their protector.
One cold day in autumn she went to the Bladebright dwarves to buy a fine jewels. The Bladebright dwarves had just finished crafting a masterpiece for their king under the mountain, and as soon as Belesaria saw it she demanded to buy it. The dwarves refused, Belesaria offered more for it, end still they refused. Vowing vengeance for this slight, she stormed off.
When Belesaria returned, she told her husband that the dwarves would not sell her their fine work, only their trinkets, and that they said she was not fit to wear anything more than that. The Mage-lord was angered at his wife's words and swore to teach the dwarves a lesson.
Returning to the Bladebright delvings, the Mage-lord threatened the dwarves with a sorcerous curse if they would not pay him a great tribute of gold and worked steel as an apology for their insults. The dwarves refused, but, knowing the power of a mage's wrath, the dan and all their kin gathered what they had and left to dwell with cousins under the mountains to the north. Their champions remained behind to fight the Mage-lord and were destroyed, never to be avenged. To this day, the Bladebright dwarves will render no aid to descendants of House Morn, including their only male heir, Randal Morn.
