The Vajra Sword is believed to be forged from Vajra, the hardest substance described in ancient mythology. When wielded, it concentrates immense force into a single decisive strike capable of cutting through any material, structure, or defense.

The weapon responds only to absolute certainty of intent. Hesitation causes the stored force to disperse unpredictably, often damaging unintended targets. Repeated reliance on the sword gradually conditions its wielder to resolve conflict through destruction rather than restraint.
