The Kobold Invasion

In the Dwarven year 1888 AS, King Argun Ter Aaldenbur died, and the council was set in disarray for many months. After deciding on appointing Councilman Babnar Eldine to the throne, the scoundrel Yimir Barkun took to plotting against the Forge King.

Yimir's Betrayal
Yimir quickly left the basin, in search for a way to dethrone the king and claim the power he craved. He found his tools for his coup in the Gnollish Wastes, where the Bronze Dragon Barunan and his legion of kobolds had settled. Yimir promised them power and riches to undermine the Dwarven Kingdom. With the hordes of lizardmen at his disposal, he put them to work, digging beneath the basin.

After many months of digging, the kobolds broke through to the Underdark, revealing the hidden Drow and Duergar. With their combined forces, they broke through the crust of the earth and began their seige. Thousands were slaughterd in their homes, and buildings were pillaged and destroyed. Those who were not killed were pulled into the Underdark to be slaves of the Duergar. The sacking continued for 5 days before help arrived.

The Salvation of the Dwarves
Almost as soon as the invasion began, a trade caravan leaving the city saw the flames, and rushed towards the Orcish stronghold. They gathered as many hands as they could and returned to the basin. By then, most of Ter Aaldenbur had been destroyed, but the dwarves did not give up hope. With their new allies, they were able to drive back the underground menaces, and sealed the entrance to the Underdark, forsaking those who had been captured. Barunan escaped, and her brood is said to dwell beneath the surface to this very day.

The Aftermath
Yimir was found with his spine shattered near the steps of the mountain. He was nursed back to health, and put to trial for treason. He was found guilty, and was executed by beheading. The Forge King Torgor, with his kingdom in shambles, recollected his people, and gave them hope, that they would rebuild, and be stronger than ever, and that it was thanks to the orcs that they survived, and they were forever in their debt.
