Hammer of Thor

Gnosis 5. These hammers are forged from silver-laced iron and cooled in the blood of freshly-slain enemies. Each hammer inflicts Strength +3 damage and causes aggravated wounds. As with Thor's hammer, Mjolnir, a hammer always returns to its rightful owner. There are seven of these hammers, and most are in the hands of the Jarls of various powerful septs. Killing blows from these weapons send out a powerful thunderclap; this does no damage, but announces to everyone in the vicinity that a foe has fallen.
