There are stories that dwarves tell their children, of a beautiful giant princess who visits their dwarven Hearthmother. The princess arrives in a floating cloud castle and spends many days visiting. Some say that the two women speak of ancient times long since past. Some say that if you stand outside the door to their chamber you will hear laughter. The kind of laughter that defines true friends.
Upon her departure the princess always leaves a gift for the dwarves. Something that she has found on her travels. The dwarves return this kindness and once gave a great gift of mithral. It is unknown what shape that gift took, but there has never been a greater gift of mithral given to anyone.
The tale of the cloud princess is something of a fairy tale. No dwarf of the youngest generation has ever seen her opalescent tower floating over the mountain. But, her story keeps getting told and many dwarf children look to the clouds hoping to catch a glimpse of her approach.
