One day the mining family shut the doors of their thaig. They spoke not to their noble patrons, nor their king, and not even a visiting Paragon. Days passed in silence before the doors to Valdasine Thaig opened. Anxious partners discovered it empty. Not one soul remained—no bodies and no sign of what had happened.
House Valdasine only left a staff of strange metal behind. It looked like lyrium and chilled one's heart like a remembered sorrow. The king sealed the staff inside the thaig, and no dwarf ever ventured there again.—As recounted by Shaper Merta
