A legendary weapon of old, the Thundermace is made from a great hunk taken from an unfeasibly large foundation stone from the base of a skycastle. The great weaponhead is bound with meteoric iron onto a long, stout tree trunk. When brought down over the head, the accumulated force of several tons of masonry explodes outward from the point of impact. It is said that the rumbling aftershocks of a blow from the Thundermace can be heard for miles and there have been several times in its storied history when particularly prodigious blows have started avalanches.[1a][2a]
