Mjolnir

Mjolnir is the magical hammer of Thor. This hammer slays any giant it hits, and it never misses. Commonly, the hammer is thrown and returns to Thor. It can be thrown any distance, and as long as there is a target in sight the hammer hits. Another property of Mjolnir is that of throwing a bolt of lightning, up to sighting distance. The intensity of the bolt is controlled by Thor himself. Lastly, the hammer shines with a pale blue light, warning Thor of any imminent danger nearby. Only beings with great strength may pick up and carry this item of power, and only Thor avatar himself may use Mjolnir.

Mjolnir was forged eons ago, but it is known that she -- for "Molly" is an intelligent weapon -- was forged at nearly the same time as Lula, the intelligent sword currently wielded by Prince Dave of Udrogoth. They consider each other to be sister weapons.

Note: Mjolnir originally appeared in this form in Legends & Lore for the AD&D game from TSR. Additional information has been drawn from the Dave the Barbarian TV show. Her use here is for the purposes of providing context for the campaign only.
