The Sixth Ruin was the sixth occurrence in the Cycle of Ruin, peaking around the year 11900 BA. Like previous occurrences it brought widespread death and destruction to Addar and beyond, but the city of Ishvatur in the ancient land of Kor withstood the worst effects and became a center for magical wisdom and learning.
Nations known to have arisen in the wake of the Sixth Ruin include Har'reg, the Kingdom of Rinillion, the Principality of Ashkeron, and the Craleus Dynasty.
