"The Hammer"
At one point, this weapon was a major focal point in the Brood campaign. Discovered by Lokan Banderez and Mathizar Azellius, it has since switched hands many times.
When found, it was being wielded by a giant golem, made entirely from clay, attacking the party for some unknown reason.
The weapon is oversized and unwieldy, but capable of inflicting massive amounts of damage, able to destroy nearly anything it is employed upon.
It is for this reason it is suspected that "The Hammer", as it has been called, is not an item of earthly manufacture. Some suspect that whoever made it may come looking for it again someday.. and woe to the holder of it then.
