Th remaining civilian population fled to Feo Berkana, and the Master of Caves and Mines, acting as a representative of the Regency Council approached the White Dragon Lord to offer the servitude to Olasird'arc Haylilyal. Since the Quagoa had vanished in the early days of the Incident, the dragon was without those who could mine gold and precious gems. It was believed by the dwarves that the dragon would accept their labor as a substitute.

Furthermore the dragon refused the dwarves request for protection as it and the family of frost dragons had no use for wealth anymore as the end of the world was coming. To the dragon no matter what they did or who they joined with, it would not be enough to protect them from the approaching death.
