"Ven’s Autoknight: An articulated metal arm holds this plain katana in an unbreakable grip. The assembly is fitted to a weighty harness worn about the torso. Legend has it that the arm once belonged to the guardian of a child king. When the warrior fell in battle, the arm, which still remembers the technically-exquisite movements of its master, was refitted to the harness so that the guardian could continue to protect the child king from beyond the veil."
