Artifax in the BrikVerse are Items with Character. That is, they always have epic stories attached to them, from legendary origins to the great deeds of the heroes who wield them. They are lesser than The Nine Artifax of Pre-Creation, which represent the most powerful items in the BrikVerse, but greater than Heroic Items, which represent merely powerful but not individually storied items. A great many SigFigs wield these potent items, often weapons, sometimes not, but a great many others have been destroyed, lost, or retkonned over the ages. Some are yet out there, in the mysterious darkness of space, waiting to be found and for their great power to be brought to bear.
The following are known BrikVersian Artifax:
Literal defecation, crucified on a stick, which is revered and wielded by Dungans.
The blood alloy mega sword of BFenix, protector of the Metal Realms.
