The Quartz Mountain is where the legendary dragon Ocvist reputedly lived. The beast was allegedly bested by Yarpen Zigrin and his band of six dwarves. It was said to have a hoard of treasure which was said to include jewels like sapphires of previously unknown colours and diamonds the size of cherries.
According to Dandelion, a ballad exists which tells the tale of the brave Yarpen defeating Ocvist. The bard, however, considers this ballad to be rather boring as it is not one of his own.
