Krolmir, wielded by Thorim.
Krolmir, being returned to Thorim
Krolmir, Hammer of Storms is the personal weapon of Thorim the Stormlord.
When Thorim's wife, Sif, was slain by his brother Loken, Thorim threw the hammer to the earth with all the power and rage he possessed, creating the site now known as Thunderfall.
As his final act, King Arngrim cast a rune on the hammer to prevent his enemies from claiming it. When Thorim's ties with the Sons of Hodir were strengthened, many years later, King Jokkum returned the hammer to its rightful owner.
Its relation to the similarly named [Vulmir, the Northern Tempest], which is found in the Cache of Storms, if any, is unknown.
Krolmir is based on Mjölnir, the hammer of the Norse god Thor.
