She has Iron ore mined from the deepest parts of the 4th Layer, which has soaked in the Abyss's forcefield. It naturally channels spatial distortion that is Used for hilts and scabbards. Because the Ethereal Tree creates endless food, its wood possesses boundless life-force energy, preventing the Kitsunes' black thunder from eroding the weapon. To honor the tribe's pact with the Abyss, the craftsman refines the physical remnants of the human souls sent down from the surface, turning the absolute despair of wicked surface-dwellers into a sharp, durable edge. Forging in the Spatial Rift: The forge isn't heated by coal; it is heated by the tribe’s black foxfire. The craftsman must shape the metal while the anvil itself is warping through dimensions due to the tribe's passive spatial manipulation. As they hammer the metal, the craftsman must chant prayers to Inari. Since the tribe manipulates fate, the craftsman doesn't just sharpen the blade; they "lock" the weapon's timeline so that it is fated to always strike its target, bypassing the Abyss's creatures. These weapons ensure the tribe doesn't have to go angry all the time to manifest the swords.
