Hearing the name Storm of Crows might bring to mind fantasy games or dark forests, yet the real item comes from Chinese military records of long ago. Tod Cutler at Tod’s Workshop took the idea of a cup arrow, the romantic label for a bundle of smaller shafts, and set out to launch it from his Tzusun siege crossbow. That machine copies the Ox Bow design, a triple-bowed frame that once required oxen to draw and sent broomstick-sized bolts downrange with hundreds of joules of force. Single large arrows could punch through armor or men, but they left groups of infantry largely untouched unless the targets lined up neatly. Chinese engineers therefore developed a way to send many short arrows at once, creating a spread of hits that covered more ground.
