The Thunder Blessing, also known as the Thundering,[1] occurred in the Year of Thunder, 1306 DR, and was the dwarven god Moradin's gift to his people which dramatically increased the reproductive rate of dwarves.[2] Moradin called a council of the dwarven pantheon to find a way to increase the number of dwarves. The council decided to split each existing soul into two when they were reincarnated.[3] After the Thunder Blessing most dwarven births were twins.[4][note 1]



  1. The Grand History of the Realms says that nearly one in five dwarven births resulted in twins, either identical or fraternal, which is clearly not "most".
